…reaming Introduces an in-memory broadcast event bus (changestream.py) that the ingestion processor publishes to after successful upserts/deletes. A new WebSocket endpoint at /xrpc/science.alt.dataset.subscribeChanges streams these events to subscribers with cursor-based replay from a bounded buffer.
