With 5 x 10 MB rotation the daemon log covered about three hours on the
audited machine, mostly one of a few lines repeated:
- "Failed to submit extraction ...: entity_graph_jobs channel full"
(11k lines) from GraphComponent, echoed per batch by PostIngestQueue's
"KG batch failed", plus "Entity channel full, dropping job";
- the per-document "Title+NL extraction for <hash> in N ms" info line;
- session-watcher scan/indexing warnings retried every pass.
Add yams::common::LogRateLimiter, a small lock-free helper that admits
one message per interval and reports how many it held back ("(N similar
messages suppressed)"), and use it at those sites (60 s for the queue
paths, 10 min for the session watcher, including its first-failure
warning per path). The Title+NL timing line is per-document progress
and moves to debug. The drop counters are unchanged, so status still
shows the full numbers.
