Move core Drive FS implementation details to the `internal` package, simplifying the public API. Introduce a resource pool (`pool.Pool`) for managing Google Drive service clients to potentially improve performance and handle rate limits more effectively. Refine error handling and path manipulation. Remove old example and deprecated top-level files (`file.go`, `gdrive.go`, `ro.go`, `rw.go`).
