Fixes to sign-in and session handling so tools stay available after signing out and back in.
What changed:
- Fixed an issue that caused tool calls to fail after signing out and signing back in
- Improved how the app recovers from sign-in changes so it stays responsive and connected
Why it matters: Re-authenticating won't break your workflow. Expect fewer interruptions, fewer unexpected errors from tools, and less need to restart the app after signing in again.
