Replace the lock file mechanism with PID+start-time based stale detection so that no cleanup is required on process death. When both org and app token locks were held, the first signal handler to call os.Exit() would kill the process before the second handler could delete its lock file. The orphaned lock file then caused the next invocation to wait ~128 seconds in an exponential backoff loop before forcibly deleting it. The same issue occurred on SIGKILL, OOM, or any non-signal death. Lock files now contain the holder's PID and process start time as JSON. On acquisition, if a lock file already exists, the recorded process is checked for liveness via gopsutil. Stale locks are reclaimed immediately with no backoff. Atomic O_CREATE|O_EXCL prevents races between concurrent acquirers. Also adds a companion .url file so processes waiting on an active lock can print the auth URL for the user.
