/**
 * Stream in-process poll events over SSE.
 *
 * This is the fast path for agent/tool/action writes that happen in the same
 * server process. The regular /poll endpoint remains the cross-process and
 * serverless cold-start fallback because it can detect DB timestamp changes
 * even when the write happened somewhere this EventEmitter could not see.
 *
 * Also forwards awareness change events (cursor/presence updates) so
 * connected peers receive cursor moves push-style instead of waiting for
 * the next poll cycle. Polling fallback keeps working — cursors degrade
 * gracefully to poll cadence without SSE.
 *
 * `state` defaults to the process-wide instance so self-hosted apps are
 * unchanged; the hosted gateway passes a per-app instance to fan out that
 * app's events (awareness stays on the process-global emitter and is a v0
 * gateway Non-Goal).
