M3: working desktop app + browser pairing channel

- Builds and runs (tauri build --debug); placeholder icons; persistent VaultCore::open in the
  OS app-data dir; Secret Key remembered on the device; tray keeps the app serving the extension.
- Auto-lock: idle (system idle on Windows/macOS, in-app activity on Linux), screen lock, sleep.
- Local IPC for kestrove-nmh: 0700 dir + 0600 Unix socket with peer-uid checks; Windows named
  pipe (first instance, local only, user DACL, client SID check) behind cfg.
- Pairing channel: X25519 → HKDF → 6-word fingerprint confirmed in both UIs, per-connection
  session keys, AES-256-GCM with strict counters. Test vectors shared with kestrove-browser.
- Broker: query/fill/totp/save with origin re-checks; pairing and save prompts in the UI.
- kestrove-nmh relays ciphertext only; native-host installers for Linux/macOS/Windows.
- Tests: unit tests, tests/nmh_stdio.rs (real kestrove-nmh over stdio), examples/test-host.
