- Save finished jobs to registry (24h TTL) so they survive TUI restart
- Fix PermissionError in PID check incorrectly marking alive processes as dead
- Handle CancelledError explicitly to preserve running status on TUI exit
- Tail log files for reconnected running jobs instead of showing stale output
- Detect actual return code from log content; show "?" for unknown status
