[Bug] Network interruptions can lead to false positive OAuth token expiration errors and a degraded application state

Disrupted network connections can put Claude Code into a broken state where it thinks that OAuth
access token has expired, and any further commands entered results in claude code reporting:

Please run /login · API Error: 401 OAuth access token has expired. Re-authenticate to continue.".. Closing the session and re-opening it fixes the issue.

Closing the session and re-opening claude code fixes the issue.

This has happened multiple times, always during transient network outages.

I checked for related issues and found others reporting problems with unexpected "API Error: 401.."
errors, but none appeared to report the association with network issues.
