Merge remote-tracking branch 'origin/main' (13ea35973c) into brennanb2025/nc-reasoning-row

Conflicts:
- journal schemas: main's shared turn-lifecycle fields kept; the thread goal stays in its own module.
- journal terminal settlement and the dead-generation sweeps: main's turn-aware call ending
  (`terminalAgentJournalBody`/`runningCallEnd`) plus the branch's ending of an open reasoning row.
- Codex settlement: main's turn end for running calls is now an option of the branch's
  `interruptedCodexItemBody`, beside the end time that closes reasoning; the turn passes both.
- runtime: main's agent registrations; the Claude registration now carries the thinking-display
  support the branch's runtime deps hold (it was dropped, so no Claude launch asked for readable
  thinking), with a runtime test.
- renderer: main's row typography threads through the branch's slots hook; the live line takes main's
  text-size class; the reasoning row and body follow main's restyle (chat text size, faint tone,
  upright prose through NativeChatMarkdown); the collapsed reasoning estimate stays beside main's
  typography-scaled line height.

 - **File paths**: Use `path.join` or Electron/Node path utilities — never assume `/` or `\`.
 - **Windows terminal shells**: `--shell` picks the shell a terminal _is_; `--command` is typed into whatever shell the host spawned, so a shell choice routed through `command` silently becomes a child process. See [`docs/reference/windows-terminal-shell-selection.md`](./docs/reference/windows-terminal-shell-selection.md).
 - **Windows setup scripts**: the setup/issue-command runner is a `.cmd` batch file unless the script starts with a `#!` line — never derive that from the user's terminal-shell preference, and never launch a `.cmd` runner with a bare `cmd.exe /c` from a Git Bash pane (MSYS rewrites the `/c`). See [`docs/reference/windows-setup-shell.md`](./docs/reference/windows-setup-shell.md).
-- **Windows child processes**: start them through `runProcess`/`spawnProcess` in `src/shared/child-process/` — never `child_process` directly. It pins `windowsHide`, refuses `shell: true`, and encodes `.cmd`/`.bat` arguments so neither `CommandLineToArgvW` nor `cmd.exe` mangles them. A ratchet test fails on any new direct import. Recognised npm/pnpm `.cmd` shims are resolved to their real target so the spawn skips `cmd.exe` entirely; see [`docs/reference/windows-cmd-shim-resolution.md`](./docs/reference/windows-cmd-shim-resolution.md) before adding a shim shape or debugging one.

 - **Ripgrep**: Orca bundles `rg` for every platform, WSL, and SSH remotes. Spawn it through `spawnBundledRipgrep` (main) or `resolveRelayRipgrepCommand` (relay), never a bare `'rg'` — Windows resolves a bare name in the spawn cwd before PATH. Don't add git/readdir fallbacks locally; the relay's chain exists only for hosts an upload never reached.
 - **Windows process enumeration**: read the table through `src/main/windows/windows-process-table.ts`, never by forking `powershell.exe`. See [`docs/reference/windows-process-enumeration.md`](./docs/reference/windows-process-enumeration.md).
 - **Windows MSYS/Git Bash panes**: their children break away from the per-PTY job unless it is created without `JOB_OBJECT_LIMIT_BREAKAWAY_OK`, and a `conpty.node` built before that fix passes every existing gate. Before changing the per-PTY job or debugging `windows-msys-job.win32.test.ts`, read [`docs/reference/windows-msys-job-breakaway.md`](./docs/reference/windows-msys-job-breakaway.md).

Stage at least 1,000,000 xterm cells, hide all six warm managers, emit an initial working title followed by 30 timed real-PTY spinner frames and a final idle title per worktree, and observe a second real session-tabs subscription plus the production renderer store. Require exactly two transport envelopes and two title mutations per worktree, no decorative title crossing either boundary, and positive decoded-envelope bytes. Enable ordinary parking with the lossy retention budget disabled, require exactly one mounted manager and five parked tabs, at most 45% retained cells, no more than 16 MiB heap growth, and under 500 ms timer drift. In headed mode, require the host renderer to remain on its original workspace with zero target terminal managers mounted throughout client park, reveal, and live I/O. While a tab is parked, require authoritative terminal.read to observe new PTY output; reveal it and require the original PTY, a marker within the requested 5,000-row history, the parked marker, and post-reveal input/output. Drive 24 real PTY title trackers in distinct worktrees through 40 decorative spinner frames each, then 40 spinner frames alternating with Cursor's bare native identity redraw, using fake clocks. Require all 2,880 raw chunks exactly and zero host session-tabs publications, serialized bytes, renderer apply calls, and renderer store mutations. Continue decorative evidence beyond 30 minutes, require exactly one refresh per worktree per 15-minute lease through a FIFO spaced by at least 50 ms, and require all 24 viewer statuses to remain working and fresh; then require one exact semantic idle transition and one visible-output chunk per PTY. Require ordinary and interior-Braille title changes to publish. Drive 64 host PTYs through ten 80 ms synthetic title frames, require zero paired client events after the first frame per PTY while all 640 local frames remain observable, attach a late client and require one current frame per PTY, then require semantic bell and idle transitions on both clients. Reconstruct a legacy subscribed stream with no outputPause capability, hide a chatty pane, require no hidden xterm writes, reveal it, and require one authoritative snapshot plus continued live output. Drop and acknowledge output only for one original paired-client stream, prove the fixture process consumed input while the host model advanced and the client stayed stale, then require the command snapshot probe to replace that stream, repaint exact fixture output, preserve authoritative PTY identity and target-tab cardinality, and resume live I/O. For a client without a delivered sequence, require the first numeric probe to establish a baseline without replacement, a same-sequence probe to remain attached, and a later advanced probe to replace only that stream. Withhold the first encrypted shared-control ready frame, start one RPC, trigger a status-probe refresh, and require two connections, one host delivery, successful response, and zero retained request bytes. Admit 128 active streams, reject the 129th as retryable, release one stream, then require the retry to attach and publish a snapshot without multiplying retained subscribers. Disable terminal.paired-parking.v1 and require the same oracle to fail before parking, while the legacy limit-one fallback separately passes.

- * grow, and that the entry is read before it ships rather than found on a device.
- *
- * What is NOT here is the point of the census. `files/[worktreeId] -> files/preview/[worktreeId]`
- * is absent because the preview declares no more than the explorer, so that hop stays in the
- * document — which is C3.1's pairwise pin, now a consequence of the rule rather than a rule of its
- * own. Absent for the same reason, and measured rather than reasoned: the four hops the worktree
- * list and the history screen make into the explorer and its preview, which left this list when
- * those two declared the `externalLink` their own protocol wall reaches and took it from 23 rows
- * to 19. The four now declare the same four grants, so a tapped file costs no native frame and no
- * second bridge session.
- *
- * What remains beside the session rows is twelve: four openers holding no `native.clipboard.write`
- * into the three routes that ask for it — tasks, the hub and review.
- *
- * Absent for the same reason, and the reason C4 registered its two routes in one PR:
- * `source-control ⇄ review` in both directions. The hub's rows push review and review replaces
- * back, and the two declare the same five grants, so both hops stay in the document. Either one
- * landing alone would have put a handoff — a new native screen and a new bridge session — between
- * a changed-file row and its diff.
- *
- * The seven C7 rows are the same rule with the arrows all one way: every one `X -> session`, one
- * from each other page route. The session screen's thirteen grants are a strict
- * superset of every other route's, so nothing can reach it under the grants it was opened with —
- * and nothing it pushes to leaves, because its own seven targets each declare a subset. A row in
