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.
