feat: add Windows sync script

- Phase 1: One-way sync (Windows -> Server) for main folders
- Phase 2: Bidirectional sync using rclone bisync for _LLM_Sync
- Auto-detects rclone and BenjaminTeam folder paths
- Comprehensive logging to %LOCALAPPDATA%\JingTian\logs
- Supports verbose output with -VerboseOutput flag
