Paul Trowbridge a6e6efd36e Switch /data endpoint to Arrow IPC stream with pg cursor batching ... Server streams rows from a pg cursor in 10k-row batches, building Arrow record batches incrementally and piping them as chunked HTTP response — Node.js heap stays bounded regardless of dataset size. Client fetches as arrayBuffer() and loads directly into Perspective worker (native Arrow path, no JSON deserialization). X-Row-Count header drives a non-blocking banner for datasets >= 500k rows. validCols now derived from col_meta rather than from row keys.
