Previously, every query would enumerate all datasets on cloud storage and load all of them, causing ~10s latency with 20+ datasets on GCS. Now the query parser extracts which tables are actually referenced (via node_labels() and relationship_types()), and only those specific datasets are loaded. Paths are computed directly from the root path without enumeration. Fixes lance-format#87 Co-Authored-By: Claude <noreply@anthropic.com>
