Explanation
Issue [
#6] requiresfirefox-cli setup native-hostto create the Windows native-messaging registry entry.registerNativeMessagingHostwrites the manifest and then writes the per-user registry value through PowerShell. The CLI uses this path for targeted setup and for plainsetup. Tests cover registration, stale-value replacement, repeated registration, dry runs, write failures, and the 30-second timeout.

Explanation
The changes remain connected to issue [
#6]. Plainsetup,doctorrepair, JSON output, dry-run behavior, diagnostics, documentation, release checks, and Windows integration tests support or verify native-host registration. The extension manifest change is formatting-only and supports the reported formatter check without changing semantics. No unrelated change is demonstrated.

@packages/native-host/src/windows-native-messaging-registry.ts:
- Around line 183-211: Update runPowerShellProcess to enforce a bounded timeout
for the spawned PowerShell child, using the established timeout duration
expected for this registry operation. When the timeout expires, kill the child
and reject with WindowsNativeMessagingRegistryError containing the timeout
diagnostic and captured stdout/stderr. Clear the timer on child error, stdin
error, and close so completed processes do not trigger a later rejection.

use windowsManifestFilesystemPath, or otherwise preserve manifestPath when it is

Both JSON setup forms produced parseable error output on stdout, empty stderr, and exit 1.doctor --fixrestored one; exit 1 was expected because the isolated environment had no paired Firefox extension.--fix, preserve the filesystem cause, and verify that the directory remains intact.

The prior Ubuntu and macOS validation jobs stopped at Biome
format:checkonpackages/extension/src/manifest.json, unchanged frommain; the user-approved formatting-only fix is in61036f0, and a focused formatter check passed. The Windows validation job in that run exposed eight setup-registration test failures because tests used host path semantics for simulated Windows and macOS paths. The test helpers were corrected; a follow-up review found one remaining registry-denial test read that bypassed the helper, fixed in0b74676. Commitb0b02b0adds a 30-second PowerShell registry timeout with captured-output diagnostics and focused automated coverage. The focused changed suites, affected package typechecks, Biome, and ESLint pass locally. Run 39776552880 passed Ubuntu/macOS validation and the security/package checks but Windows validation failed because the new doctor JSON test searched serialized JSON for a raw Windows path. Commit 4071c8d parses JSON and checks the manifest path and error fields structurally; four focused cases pass locally, as do CLI typecheck, Biome, and ESLint. That failing run predates 4071c8d and does not validate the correction. Live Windows registry and Firefox behavior remain unverified.Windows registry integration
