* fix(ports): keep the app responsive when security software slows process creation Orca ran the workspace port scan's probe commands (lsof/ps on macOS, netstat + powershell.exe on Windows) directly in the Electron main process. libuv performs process creation inline on the calling event loop, which in the main process is the browser UI thread, so an endpoint-security module hooking CreateProcessW froze the whole window for the length of the spawn. The same stall also produced a false diagnosis: the 4s command watchdog was armed before execFile (local-workspace-port-scanner.ts:389 -> :410), so its deadline had already passed by the time the command started. Every scan on a hooked host reported a command timeout, tripping the 60s -> 5min backoff and the "Port scanning is temporarily paused after a command timeout" banner even though the commands themselves were healthy. Probe commands now run on a lazily created, unref'd worker thread with FIFO one-at-a-time dispatch, and the watchdog is armed after execFile returns so it measures the command rather than the spawn. Node's own execFile timeout kill (killed: true) is classified as a command timeout, keeping the backoff working for genuine hangs. A scan that observes a stalled spawn skips its optional metadata commands for that cycle, capping a hooked-host scan at roughly one stall instead of three. Closes #11161 * fix(ports): keep advertised URLs when a stalled spawn skips port metadata Review follow-up on #11161. The stalled-spawn early return handed scanWorkspacePorts raw ports with no cwd/commandLine, so every port failed attribution and reconcileAdvertisedUrls told the watcher each worktree's listeners had vanished. shouldEvictAfterScan then deleted every cached advertised URL and broadcast a removal event; those URLs are only ever captured from live PTY output, so the dev-server link was gone until the server restarted. The scanners now report metadataAvailable, and reconciliation is skipped for a scan that never gathered attribution evidence. The skip is also no longer self-perpetuating: on an EDR-hooked host every spawn stalls, so gating purely on the current scan's spawnMs made every port permanently external (Stop refused with 'Only workspace-owned local processes can be stopped here.'). Metadata is now re-probed on the scan after a skip, matching what the comment and test name already claimed.

Cleanup now retries and, on Windows only, tolerates a residual lock code instead of reporting it as a launcher regression. Co-authored-by: Orca <help@stably.ai> * fix(ports): scope the metadata skip away from attribution-dependent scans The metadata skip was a process-wide parity flag, so Stop and the localhost-label allowlist could land on a degraded cycle and reject a port the panel had just shown as workspace-owned. Give those callers an explicit requireMetadata option, and carry the previous cycle's listener metadata forward so a skipped background scan no longer republishes workspace ports as external. Also pin the watchdog ordering: the stall in the execution test was shorter than the watchdog budget, so a watchdog armed before execFile still passed. * build: guard worker-thread entries against electron imports (#11161) Electron's module is not registered on worker threads, so require("electron") throws "Cannot find module 'electron'" inside a main-process worker and kills it at startup (verified on Electron 43.1.0). plain-node-entry-guard covered only forked plain-Node entries, so the five worker entries relied on hand-written "must stay electron-free" comments. The port-scan probe worker is one import away from port-scan-command-client.ts, which deliberately contains require('electron'). A violation there fails closed at runtime while every unit test still passes, because the client's require is try/caught on the main thread. Covers stt-worker, warp-theme-parser-worker, session-scanner-opencode-sqlite-worker-entry, main-thread-hang-watchdog-entry and port-scan-command-worker-entry. The scan is transitive over the emitted chunk graph, so a shared chunk that reaches electron is caught too.

Co-authored-by: Orca <help@stably.ai> * test(ports): pin the packaged-asar worker entry path resolveWorkerEntryPath's packaged branch never runs in dev or e2e, so the path construction had no coverage. Split the electron read out of it and unit-test both layouts.
