- PR #73918: fix: make stale-stream detector content-aware to catch heartbeat-only providers (#73872)

These members all concern the stale-stream detector in an agent, focusing on making it content-aware so that SSE heartbeat frames or empty stream chunks do not postpone the stale timeout. One is a bug report and two are fix-oriented pull requests; titles alone do not show their status or outcome.
