plugins/logging/v1.8.1

## Plugin Release: logging v1.8.1

- chore: upgraded core to v1.9.1 and framework to v1.7.1
- feat: MCP tool log rows carry governance entity names alongside their IDs, written from the request context at ingestion, so nothing is resolved on read (#7154)
- feat: endpoint-attributed MCP observations are written onto both the pending and the final MCP tool log entry, with the observation snapshotted so it cannot alias across async entries (#6959)
- feat: cost recalculation honours time-of-day peak and off-peak pricing, scaling usage-based charges by `off_peak_cost_multiplier` when a request falls outside every declared peak window (#6575)
- feat: GA realtime transcription sessions are logged and priced through the standard pipeline with transcription-aware pricing (#7089)
- fix: a request whose caller disconnected before the upstream finished is logged and finalized deterministically rather than roughly half the time, so abandoned requests no longer leave a log row stuck in its pending state (#6972)
- docs: clarified that `CountRecalcTargets` reads a materialized view that can lag, so its `Total` is an approximation rather than an exact count (#7078)
