Under the hood
Background OAuth keychain polling now skips itself when a third-party provider makes the token unused
What
A background loop that checks the system keychain every 30 seconds for a missing OAuth token now checks whether a third-party authentication provider is in use and no active process actually needs the OAuth token. If both are true, it stops re-checking the keychain each cycle instead of unconditionally polling it.
Why
This avoids pointless repeated keychain checks when a third-party login provider has made the OAuth token irrelevant, reducing unnecessary background work.
