fix(app): do not throw from ConnectionSettings.initialize

The migration write is best-effort again. `_mode` is already the safe TUN
default in memory by the time it runs, so a failed write leaves nothing
insecure -- it only means the migration is retried on the next launch.

Throwing there was a startup brick rather than a fail-closed guard.
`initialize()` is awaited from `main()` at lib/main.dart:19, before
`runApp()`, with no try/catch and no `runZonedGuarded`; `FlutterError.onError`
and `PlatformDispatcher.onError` are installed later and would not catch it
either. The branch also runs on every fresh install, since `storedMode` is null
and `null != 'tun'`. A `setString` returning false would therefore have meant a
black screen with no error UI, repeating every launch, in exchange for no
security benefit.

Also restores two comments this PR removed from code it does not otherwise
touch -- the `_reconnect` note on why the repair path shows no rewarded ad, and
the explanation of how an orphaned proxy outlives the app process -- and drops
a stray 'ass' from the legacy-values comment.

The `setMode` half of the PR is unchanged: persisting before mutating memory
and surfacing failures to the UI is the right behaviour.

 ---
 
+## [3.3.4] — 2026-09-02
+
+### Added
+- **OS-level session-expiry enforcement.** The VPN service now holds an absolute
+  deadline and tears the tunnel down on its own clock — a main-looper handler
+  plus an `AlarmManager` exact alarm (falling back to an inexact alarm on
+  Android 13+ when exact alarms aren't granted). The app pushes
+  `now + expires_in_seconds` on each session sync, so a session ends even if the
+  UI process has been killed.
+- **Session survival across process death.** The service persists the active
+  session and re-establishes it when Android restarts it (`START_STICKY`).
+- **Support-ad extension reflected immediately.** A rewarded "Support us" ad now
+  forces an immediate server sync, so the countdown and expiry deadline update
+  without waiting for the next heartbeat.
+
+### Changed
+- **Session-status beacon slowed.** Foreground poll: 5 s → 60 s; background poll:
+  30 s → 60 s.
+- **Background-reliability guidance.** The "Always-on VPN" settings deep-link was
+  removed; the battery-optimisation exemption remains, with expiry now enforced
+  by the service itself.
+
+### Removed
+- Legacy `ass` connection-mode migration — unrecognized persisted modes now
+  default to TUN.
+
+### Security & privacy
+- Session credentials and the per-user VLESS UUID are now held app-private on
+  disk (`active_session.bin`) for the session's lifetime and removed on
+  disconnect or expiry. Previously they were memory-only.
+
+---
+
+## [3.3.3] — 2026-09-01
+
+### Fixed
+- **The session clock stayed at 00:00:00 on a live tunnel, and the notification
+  countdown froze with it.** `SessionTimer` is built lazily, so when the app reattaches
+  to a tunnel that outlived its UI process, `VpnConnection` had already reported
+  "connected" before the timer existed — and a change listener does not replay events
+  it was not present for. The timer now evaluates the current connection state once at
+  construction instead of waiting for a transition, and is created eagerly alongside
+  `VpnConnection`. Because the timer is what pushes text to the foreground
+  notification, a stopped clock also meant a frozen countdown; both come from this.
+- Resuming the clock no longer requires `adoptedRunningRuntime` or a previous
+  successful sync, both of which are false in a freshly started process. A connected
+  tunnel with a stopped clock is now always treated as something to resume.
+
