5 commits landing 5 independent P2 fixes:
- ba5d218 inactivity timer resets on all non-passive messages (READ_ONLY_CONTENT_CALLABLE exclusion set in session-timer.ts; index.ts inverts the gate)
- 35444e0 state.gitHost cleared on session expiry (alongside state.manifest)
- e43f121 teardownSettingsCommon extracted; both settings.ts + settings-vault.ts call it (parameterized over each file's own activeKeyHandler module variable)
- 39fac68 Promise.allSettled with per-slot fallback in devices.ts (list_devices+list_revoked + sshFingerprint map). trash.ts is a no-op on this branch — it doesn't have a Promise.all to migrate (single list_trashed call); plan was written against a different snapshot.
- fce1962 MutationObserver scan() debounced to 200ms in content/detector.ts (no test harness on this branch — manual verification per plan note)
377/377 vitest tests pass (baseline 371 + 6 new tests in session-timer + devices). Zero regressions.
