* feat(vcs): IDEA's diff algorithm and change colouring in the diff viewer
Port IntelliJ's text comparison to TypeScript (src/features/vcs/comparison):
Myers/patience LCS with unique-element discarding, ByLine (smart matching
that skips unimportant lines, chunk optimizer, second-step correction),
ByWord (word chunks, punctuation matching, whitespace policies, line block
splitting) and ComparisonManager's compareLinesInner / processBlocks. The
port runs IntelliJ's own LineComparisonUtilTest, WordComparisonUtilTest and
SplitComparisonUtilTest cases (459 runs), converted to ideaCases.json.
MergeView chunks now come straight from these line fragments, with the
inner word fragments as chunk changes, instead of @codemirror/merge's
presentable diff. Revert and >> / << replace lines as
DiffUtil.applyModification does.
Colour changes as IDEA does: modified (blue), inserted (green) and deleted
(grey) by chunk type, a lighter line background for chunks whose words were
compared, each word fragment in its own type at full line height, a thin
bar for a fragment empty on one side, and the colours carried into the
gutters and the divider bands. New --diff-modified / --diff-inserted /
--diff-deleted theme tokens, imported from .icls DIFF_* attributes.
Add a Playwright suite over a generated git repository of diff cases,
including 10,000-line files, in every viewer mode.

The VCS viewers (diff, merge, local history) hard-coded the default mono
font, size and line height, so Settings > Editor > Font had no effect on
them. Read the editor font variables like the main editor does, and apply
fontExtension next to the caret, kept in step with the settings.

The OS clipboard's file list was only wired up for Windows (CF_HDROP), so on
macOS the project view never saw files copied in Finder: Paste stayed disabled
and ⌘V did nothing. Read and write the general NSPasteboard's file URLs
instead, so Finder's copies paste into the project view and the project view's
copies paste in Finder.

Each build's tauri-action rewrote the shared latest.json by deleting and re-uploading it, so
parallel macOS builds raced: one failed with 404 on the delete (skipping DMG notarization), or a
platform could silently drop out of the manifest. The builds no longer upload it; a new
updater-manifest job builds it once from the uploaded .sig files and fails if any platform is
missing. publish waits for it.

Python file launches only exposed the script directory, so imports of sibling project packages failed. Add content, source and test roots to the effective PYTHONPATH after environment resolution, preserving existing paths. Apply the shared behavior to Python/test process launches and debugpy launches while leaving attach and remote adapter paths unchanged.

Settings › Keymap offers Eclipse and Eclipse (macOS), built on the default presets with the bundled Eclipse keymap bindings for every action we have. Numpad keys are matched by physical key only when the active keymap binds them explicitly (other presets keep the + - * / aliases) and display as NumPad keys; undo/redo stay with the focused view.

The font pickers never read the installed fonts: they probed a hard-coded list of ~30 names with canvas width checks, so anything outside the list never appeared and the monospaced filter changed nothing. A new ide-fonts crate asks the platform font system for families and their fixed-pitch flag (CoreText on macOS, DirectWrite on Windows, fc-list on Linux/BSD), exposed as system_font_families (spawn_blocking, cached). Every font picker — editor font and fallback, terminal font and fallback, UI custom font — uses one FontSelect with prefix type-ahead, a real monospaced filter, and keeps an uninstalled selection visible.

Toolchain detection only knew fixed install locations (SDKMAN, nvm, pyenv…), so per-version managers were invisible and project-pinned versions were ignored; mise also only reaches PATH through an interactive-shell hook. JDK, Node.js, Python, Go and Maven installs under mise (MISE_DATA_DIR / XDG) and asdf (ASDF_DATA_DIR) are now detected, pinned versions from mise.toml variants and .tool-versions are resolved and used when the SDK setting is Automatic, and the managers' shims/installs are added to PATH when the login shell didn't.

Only the JVM the IDE launched directly was told the console's output encoding, so forked JVMs (spring-boot:run, Surefire, bootRun, Gradle workers), debugger-launched JVMs and Build-window builds wrote GBK on Windows while the console decoded UTF-8. Every JVM the IDE starts on Windows now gets the console encoding: java gets -Dfile.encoding alongside the std* properties, build tools and their forks get JAVA_TOOL_OPTIONS (std* only) with the IDE's own 'Picked up JAVA_TOOL_OPTIONS' line filtered, shell command lines are recognised by their first word, and java-debug launches get the matching vmArgs. The Debug console now shares the Run console's ANSI parser. Encoding helpers moved to ide-core::output_encoding.

MySQL flags text columns with a binary collation as BINARY, so sqlx reports them as VARBINARY/BLOB and cell() formatted them as 0x… — including information_schema names (utf8mb3_bin under lower_case_table_names=0, or anything with character_set_results=binary). The hex schema name was then used in follow-up queries, which matched nothing. Metadata queries now always decode text as UTF-8; result grids show hex only for true binary data. Covers schemas, tables, columns, indexes, foreign keys, triggers, routines, DDL, completion and the table editor's _bin primary keys.

When Claude Code loses its API connection or is refused, it retries on its own
for up to several minutes. The session showed only "Working…" meanwhile. It
now shows "API request failed, retrying in Ns (attempt 3/10)" with the error
in the tooltip, cleared by the agent's next output or the end of the turn.
jdtls was launched with -Xms1G and no heap cap or GC choice, so the JVM grew to a quarter of physical RAM during import and kept it. Default VM args are now ParallelGC with GCTimeRatio/AdaptiveSizePolicyWeight, -Xmx2G -Xms100m, disabled memory-mapped zips and VM-install detection, prepended as --jvm-arg so both the direct and launcher-script paths get them. User JVM options replace the matching default (heap, -D/-XX by name, any -Xlog, any GC flag drops the whole GC group).

* feat(settings): HTTP Proxy settings for the IDE's outgoing connections
Add Appearance & Behavior › System Settings › HTTP Proxy with three modes:
No proxy, Auto-detect proxy settings (the default; environment proxy as
before) and Manual proxy configuration (HTTP or SOCKS, host and port, a
comma-separated "No proxy for" list with `*` wildcards, optional proxy
authentication). "Check connection…" GETs a URL with the settings as edited
and reports the status or the error.
- ide-core: `ProxySettings` plus routing (no-proxy globs, loopback always
direct, credentials percent-encoded), the current proxy for the process,
curl arguments and child-process variables.
- ide-http: `client::build` / `client::shared` is the one HTTP client
constructor; the HTTP Client requests and the update check go through it.
- ide-tools: curl downloads (tools, JDKs, debug adapters, agent registry,
remote server) follow the setting.
- A manual proxy reaches child processes (language servers, debug adapters,
terminals, git) as HTTP_PROXY / HTTPS_PROXY / ALL_PROXY / NO_PROXY.
- The proxy password is kept in the owner-only saved passwords file
(`proxy-password.json` in the app data directory), not in settings.toml.

ide-lsp returned the same `unavailable` error whether no server was running or a running server didn't implement the request, so the UI said no language server was available, and Invoke Inline Completion said no language server provides inline completion, while jdtls was running fine (it doesn't implement textDocument/inlineCompletion). When servers are running but none supports the feature, the error now names them ("jdtls doesn't support inline completion"), and every explicit action shares one message helper: Invoke Inline Completion, go to declaration / implementation / type declaration, quick documentation, parameter info, rename, reformat, intention actions, highlight usages, call / type hierarchy, find usages, safe delete and workspace symbols. With no server running it still says no language server is available. Background requests while typing stay silent.

The side-by-side diff gets two independent options. Synchronize Scrolling (toolbar lock, also in the settings menu, on by default) scrolls both panes together; Align Changes (settings menu, off by default) pads the panes so changes line up. With Align Changes off, the panes keep their own heights and a divider of curved bands joins each change, with arrows to apply it; scrolling one pane moves the other through the matching change (anchored at a third of the height), including caret moves and the wheel over the divider. Scroll mapping and the divider look up changes by binary search, so large files with thousands of changes scroll smoothly.

java-debug runs inside jdtls and is reached through its debugServer port, but configurations that aren't Application / Spring Boot and select java-debug (a Shell Script running `catalina.bat run`, say) fell through to the generic launch template, and the adapter launcher tried to start com.microsoft.java.debug.plugin.jar as a process: on Windows that failed with os error 193, elsewhere with a misleading "debug adapter not found".
- Shell script / program configurations with java-debug start with a suspended JDWP agent injected through JAVA_TOOL_OPTIONS and attach once the JVM prints its port, so `catalina.bat run` / `catalina.sh run` can be debugged.
- Maven goals that run the app in Maven's JVM (tomcat7:run, jetty:run(-war), exec:java, or any Maven config with java-debug) are debugged through MAVEN_OPTS.
- Gradle tasks that start no JVM say why they can't be debugged; `debug.startConfig` with a single debuggable config goes through the run debug flow.
- .jar adapters are never spawned as processes, and Windows adapter lookup only accepts PATHEXT files (so npm-installed adapters pick the .cmd shim instead of the POSIX one); the PATHEXT expansion moves to ide_core::process::executable_names, shared with ide-run.
Not run on Windows; the Windows resolution is covered by tests with an injected platform.

The remote server read the login shell's PATH once and cached it, had no project-level environment, and changed environment variables only took effect after reinstalling or a manual restart.
- Every openidea-server start re-reads the remote login shell's full environment (`$SHELL -ilc env -0`), with the cached PATH only as a fallback when the shell doesn't answer.
- A project's `.devcontainer/devcontainer.json` (or `.devcontainer.json`) applies on remote hosts: `remoteEnv` (with `${localEnv|containerEnv|env:X[:default]}`, workspace variables and `null` to unset) reaches every child process through one environment overlay (terminals, run configurations, language servers, debuggers, build tools, git), and `postStartCommand` (string, array or parallel object) runs once per server start in the project root as a cancellable background task; a failure raises a notification with the exit code and the last output lines without blocking the project.
- Reload Environment (`remote.reloadEnvironment`, File menu and Find Action) re-resolves the login shell and `remoteEnv` without restarting the server, starting from the process's original environment so prepended PATH entries don't pile up; it lists the changed variables, notes that running processes keep their environment, and offers to restart language servers.
- The JSONC reader moves to `ide_core::jsonc` and is shared with ide-run.

* feat(vcs): Preview the selected file's diff in the Git Log
Selecting a single changed file in the Git Log's changes pane shows its diff

Background tasks often couldn't be cancelled, or cancelling didn't stop them:
- A cancel that arrived before the backend registered the request was dropped (build while saving files, multi-repository fetch/pull between repositories). The host now remembers early cancels (bounded, 2 min), and request ids start at a random value per page.
- There was no queue and no common cancel path: backend-reported tasks (LSP progress, deployment transfers) couldn't be cancelled, and tool installs, VCS operations and update checks had no cancel button in Background Tasks.
- Only the direct child process was killed, and JDK / tool archives were extracted without checking for cancellation.
Tool installs and JDK downloads now share a downloads queue; cancelling a queued task removes it without starting any work. Every task cancels through one path that shows "Cancelling…" and then removes it; tasks that can't be interrupted show a disabled cancel button with the reason. IdeEvent::Task carries `cancellable` with a cancel_task command, cancellable LSP progress sends window/workDoneProgress/cancel, installers, curl and tar run in their own process group and are killed as a group, and extraction checks for cancellation between entries.

Column-based editing computed columns with countColumn / findColumn, which count every grapheme as one column, and up/down and Clone Caret moved by pixel x, so block selections and cloned carets drifted on lines with CJK, fullwidth punctuation, Hangul, kana or emoji. A shared visible-column helper (UI side only, UTF-16 offsets in and out) now counts East Asian wide/fullwidth characters and emoji (ZWJ sequences, modifiers, flags, VS16) as 2, combining marks and format characters as 0, and expands tabs to the next tab stop.
It drives Alt+drag block selection, drag and Shift+arrows in Column Selection Mode, middle-drag block selection (new; not on Linux, where middle-click pastes the primary selection), the up/down goal column (kept across short lines; soft-wrapped and folded lines still move visually), Clone Caret Above/Below, the caret move after Comment Line, Tab padding to the next indent stop, and macro playback of arrow keys.

Agents can run through native drivers or any ACP agent, speak ACP v1 or v2, and be installed from the ACP Registry. Tasks gain fork, in-place edit-and-rerun, steering and usage-limit handling where the agent supports them.
- Native Claude Code (`claude` stream-json) and Codex (`codex app-server`) drivers, each served to the task machinery as an in-process ACP shim, using the newest install on PATH.
- ACP v2 with v1 fallback, negotiated on initialize; per-agent capabilities (fork, rollback, steer) so the UI only shows supported actions; usage-limit errors put the task in a `limited` status with the reset time.
- Settings › Tools › Agents lists Registry agents (featured first) to install, update and remove; installed agents update when a project opens. "More agents…" in the provider picker opens it. Registry index and downloads are HTTPS-only, release archives are checked against their sha256, and entries without one show "No checksum provided" and ask for confirmation before installing. Package names from the registry can't be passed as options to npm/uv.

Installing an update gave no feedback: app_install_update discarded the download progress callbacks and downloaded the whole package silently before restarting, the UI had no pending state, and repeated clicks started parallel downloads. Manual Check for Updates also showed nothing while checking.
The update now runs as a status-bar background task: "Checking for updates…", then "Downloading OpenIDEA x.y.z" with size and percentage (streamed over a Channel, one event per percent) and Cancel until the download completes, then "Installing…". A running check or install is shared, so clicks from the notification, the notification log, Help › Check for Updates, the toolbar menu, the welcome screen or Search Everywhere join it; the backend allows one install at a time. Failures show an error notification with Retry. After installing, the app restarts through every window's unsaved-changes check and leaves an "installed" notification with Restart in case a window cancels it. Signature verification, endpoints and updater configuration are unchanged.
