- Add SQLite database connection management with proper error handling - Implement schema for files, chunks, blobs, and snapshots tables - Create repository pattern for each database table - Add transaction support with proper rollback handling - Integrate database module with fx dependency injection - Make index path configurable via VAULTIK_INDEX_PATH env var - Add fatal error handling for database integrity issues - Update DESIGN.md to clarify file_chunks vs chunk_files distinction - Remove FinalHash from BlobInfo (blobs are content-addressable) - Add file metadata support (mtime, ctime, mode, uid, gid, symlinks)
