Subject: [PATCH] fix(cursor): save credentials after auto-detect and fix
 signal hang

- handleAuth() now calls saveCredentials() after successful auto-detect
- Handle code === null (signal kill) in daemon exit handler to prevent
  promise from hanging indefinitely
- Remove unnecessary await on synchronous functions
