feat: add --batch-run flag for weekly automated sync

- Add --batch-run flag that enables --full and --showcase
- Implement state management to track last batch run timestamp
- Enforce one-week minimum interval between batch runs
- Save state to .gitsyncer-state.json in work directory
- Show state file location in output messages
- Bump version to 0.5.0

This feature enables automated weekly full synchronization from cron or shell scripts while preventing excessive API usage.
