- Added `StartupTimingObserver` for measuring how long each processor's `start()` method takes during pipeline startup. Useful for diagnosing cold start slowness and identifying initialization bottlenecks.
- Added `StartupTimingObserver` for measuring how long each processor's `start()` method takes during pipeline startup. Also measures transport readiness — the time from `StartFrame` to first client connection — via the `on_transport_readiness_measured` event. Useful for diagnosing cold start slowness and identifying initialization bottlenecks.
