 ### Fixed
 
 - **Process Cleanup on Exit** - Closing Claudio now reliably kills all Claude backend processes across all code paths, including PR workflows. Previously, `tmux kill-session` could leave orphaned Claude CLI processes if they ignored SIGHUP. The shutdown now captures the full process tree before stopping, polls for graceful exit, kills the per-instance tmux server (not just the session), and force-kills any surviving processes via SIGKILL. The shutdown sequence is consolidated into a shared `tmux.GracefulShutdown()` helper used by all stop paths.
