Pull request overview
This PR adds a new FilesystemDataStore implementation that enables storing DataStore data on the local filesystem, allowing quickstart to publish a meta lake locally without requiring cloud storage (GCS/S3). This unblocks galexie meta lake support in quickstart and integration testing scenarios.
Key Changes
- Implements all DataStore interface methods (Exists, Size, GetFile, PutFile, PutFileIfNotExists, GetFileMetadata, GetFileLastModified, ListFilePaths, Close) for filesystem-based storage
- Supports optional metadata sidecar files (.metadata.json) with configurable write_metadata flag
- Integrates FilesystemDataStore into the DataStore factory pattern

What
Add a new FilesystemDataStore implementation that satisfies the DataStore interface. Store data on the local filesystem with configurable destination_path and optional metadata sidecar files (.metadata.json). Support all DataStore operations: Exists, Size, GetFile, PutFile, PutFileIfNotExists, GetFileMetadata, GetFileLastModified, ListFilePaths, and Close.
Why
Enable quickstart to publish a meta lake locally without requiring cloud storage configuration (GCS/S3) to support integration testing with galexie with quickstart.
