## Summary by CodeRabbit
* **Bug Fixes**
* Sign-in flows now reliably propagate richer authentication results
(user data and session type), improving persistence and reducing
intermittent sign-in issues.
* Native token handling gains a fallback for environments without
encrypted storage, improving session reliability.
* **New Features**
* User-visible warning when sign-in is session-only because encrypted
storage is unavailable.
* **Chores**
* Tooling ignore patterns updated to exclude .codex.
