Phase 4: Discreet entry point + auto-lock timer

Goal: Vault entry is not labeled "Little Black Book" or "Vault." Auto-lock when the app goes to background, with configurable delay.

Approach candidates:

Settings icon long-press (≥ 800ms) opens vault enrollment/unlock.
App-pause listener (Capacitor App.addListener("appStateChange", …)) records background timestamp. On resume, if elapsed > delay and vault is unlocked, lock it.
User setting vault.autoLockDelay = "immediate" | "1min" | "5min". Default 1min.

Outputs:

Long-press handler on Settings icon → vault entry.
App background/resume wiring in src/vault/lifecycle.ts.
Setting UI in src/screens/Settings.tsx (delay radio).

Acceptance criteria:

Settings icon long-press opens vault entry. Short tap still opens Settings.
Setting unlock → background the app for 65s → resume → vault is locked.
Setting immediate → background → resume → vault locked.
Setting 5min → background 30s → resume → vault still unlocked.
Test: simulate appStateChange events with faked timestamps; verify unlock-state transitions.

Files touched: src/screens/Settings.tsx, src/App.tsx (lifecycle wiring), src/vault/lifecycle.ts (new).

## Phase 4: Discreet entry point + auto-lock timer **Goal:** Vault entry is not labeled "Little Black Book" or "Vault." Auto-lock when the app goes to background, with configurable delay. **Approach candidates:** - Settings icon long-press (≥ 800ms) opens vault enrollment/unlock. - App-pause listener (Capacitor `App.addListener("appStateChange", …)`) records background timestamp. On resume, if elapsed > delay and vault is unlocked, lock it. - User setting `vault.autoLockDelay = "immediate" | "1min" | "5min"`. Default `1min`. **Outputs:** - Long-press handler on Settings icon → vault entry. - `App` background/resume wiring in `src/vault/lifecycle.ts`. - Setting UI in `src/screens/Settings.tsx` (delay radio). **Acceptance criteria:** - [ ] Settings icon long-press opens vault entry. Short tap still opens Settings. - [ ] Setting unlock → background the app for 65s → resume → vault is locked. - [ ] Setting `immediate` → background → resume → vault locked. - [ ] Setting `5min` → background 30s → resume → vault still unlocked. - [ ] Test: simulate `appStateChange` events with faked timestamps; verify unlock-state transitions. **Files touched:** `src/screens/Settings.tsx`, `src/App.tsx` (lifecycle wiring), `src/vault/lifecycle.ts` (new). --- --- _Decomposed from [kimi_agent_kin_app_sync#26](https://forgejo.tail018ac4.ts.net/Mark/kimi_agent_kin_app_sync/issues/26)_
