chore(release): bump version to 4.1.3

- Add process.stdin.destroy() after rl.close() in all interactive commands
  to properly release stdin and allow process to exit cleanly
- Replace raw console.log with logger methods throughout CLI handlers
- Convert manual box drawing to logger.logBox() in daemon.ts
- Standardize menu formatting with logger.info() and logger.dim()
- Improve migration output to only show when migrations actually run

Fixes issue where process would not exit after "Setup complete!" message
due to stdin keeping the event loop alive.
