implement RESTful API and remove legacy endpoints

- Created unified /api/fs/[...path] endpoint with full REST methods:
  - GET: List directory contents or file info
  - POST: Create directories using Drive_mkdir()
  - PUT: Upload files with multipart form data
  - DELETE: Remove files/directories using Drive_remove()
- Added /api/fs route for root directory listing
- Added Drive_mkdir() function to drive_server.ts using fctdrive mkdir command
- Removed legacy /api/delete and /api/upload endpoints
- Updated CLAUDE.md with comprehensive API documentation and examples
- All endpoints support authentication with AUTH: 1 header in development
- Proper error handling, file size validation, and cache revalidation
