Sweep after the main substitution found three stale references that
predated this PR but became misleading once circuit breaker was removed:
- src/Socket/socket.ts: keep-alive ping comment claimed it bypassed the
circuit breaker. Rewritten to reflect the actual reason for using
sendNode() (avoid response correlator overhead) with a brief
historical note.
- src/Socket/socket.ts: comment in sendNode() init mentioned avoiding
duplicating circuit breakers; updated to "manager state".
- src/Socket/socket.ts: queryInternal comment described a self-tripping
loop in the circuit breaker; trimmed to keep only the relevant point
about the outer-timeout race.
- src/Utils/prometheus-metrics.ts: 6 circuit_breaker_* metrics removed
(state/trips/recoveries/rejections/successes/failures) — no longer
emitted by anything in the codebase. Also removed the
initialize-with-zero call in initializeMetricsWithLabels.
