/**
 * Process-local monotonic counters for session reconnect observability, incremented one-for-one in
 * `SessionEngineLifecycle.scheduleReconnect`. Kept as plain in-process counters rather than a `COUNT(*)` over
 * any persisted table because reconnect scheduling itself is not persisted at all — there is no
 * durable source to count, and a pruned/rotated one would be non-monotonic and therefore invalid as a
 * Prometheus `counter` (a prune would look like a counter reset to `rate()`/`increase()`). An
 * in-process counter only resets on restart, which those functions already handle correctly.
