## Summary Adds two counters to the native realtime backend so we can see how much duplicate row serialization the change router does per batch. When a run changes it can match several held feeds at once (a run subscription plus one or more tag/list feeds), and today each matching feed serializes that run's wire value independently. These counters quantify that fan-out so we can decide whether a shared serialization step is worth it. ## What they measure - `realtime_native.emission_run_serializations`: total wire-value serializations performed across feeds per batch (what the current path does). - `realtime_native.emission_distinct_serializations`: distinct (columns, run) rows those serializations cover (what a serialize-once-per-batch step would do). Average feeds-per-run is `run_serializations / distinct_serializations`, and `1 - distinct / run_serializations` is the serialization work a shared step could save. Wired through a new optional `onEmissionFanout` callback on the router. No behavior change.
