- Add QueueBackendNative constant to backend.go - Add case for native queue in NewBackend() switch - Native queue uses same FilesystemPath config - Build tag -tags native_libs enables native implementation Native library integration now complete: - dataset_hash: Worker (hash_selector), CLI (verify auto-hash) - queue_index: Worker/API (backend selection with 'native' type)
- Add protocol buffer optimizations (internal/api/protocol.go) - Add filesystem queue backend (internal/queue/filesystem_queue.go) - Add run manifest support (internal/manifest/run_manifest.go) - Worker and jupyter task refinements - Exported test wrappers for benchmarking
