## Summary by CodeRabbit

* **New Features**
* Added secure, automatic auth session token refresh and request replay
for expired-token responses across Android, iOS, and Electron.
* Updated sign-in flows to manage sessions without returning tokens to
the app layer.
* Added “Devices” management UI with sign out per device and sign out
all.
  * Enabled support for both Hashcash and Turnstile captcha providers.
* **Bug Fixes**
* Improved refresh de-duplication, inflight cancellation/clear behavior,
and recovery from corrupted/invalid sessions.
* **Tests**
* Expanded auth-session, refresh/revoke, and replay coverage (Electron
unit tests, Android instrumentation tests, iOS auth date parser tests).
* **Chores**
* Removed CAPTCHA site key from build-time configuration and adjusted CI
test execution.
