Function worker_quiet_timeout_ms

src/mcp/index_supervisor.c:95–105

Quiet-timeout (ms) for a supervised worker: killed + reported as a hang if it * emits no NEW log line within the window. This is a NO-PROGRESS timeout — every * completed log line the worker tails (per-batch parallel.extract.progress every * 10 files, plus each pass boundary) resets it — NOT a total-time cap, so a large * repo that keeps making progress is never falsely killed. Default: 15 min

 * genuinely stuck file emits nothing, so this fires only on a real hang). The
 * CBM_INDEX_WORKER_TIMEOUT_S override (seconds → ms) tightens it for tests. */
