This commit implements comprehensive session resumption capabilities:

- Add --resume flag to CLI arguments with support for:
  * Index numbers (--resume 1)
  * UUID identifiers (--resume <full-uuid>)
  * Latest session (--resume latest)

- Add --list-sessions flag to display available sessions

- Add --delete-session flag to clean up sessions

- Automatic session recording in non-interactive mode via ChatRecordingService

- Session cleanup functionality with configurable retention policies

- Full integration with existing chat recording infrastructure

The implementation enables users to seamlessly continue conversations across multiple CLI invocations, maintaining context and history.
