* feat: replace console HTTP polling with persistent SSE streams Console collector now subscribes to each server node's /v1/api/events/global SSE stream for real-time state updates instead of polling /v1/api/dashboard and /health every 15 seconds. Server changes: - Emit ws_created/ws_closed events on global queue from create/close handlers - Add node_snapshot on SSE connect (workstreams, health, aggregate) - Add ?expected_node_id= identity verification (409 on mismatch) - Add health_changed callback to BackendHealthMonitor circuit breaker - Add periodic aggregate emitter thread (10s) Console collector changes: - Single asyncio event loop on one thread multiplexes all SSE connections (scales to 1000+ nodes vs thread-per-node) - Discovery loop spawns/cancels async SSE tasks per node - Snapshot reconciliation on connect, delta application for live events - Fix ws_state→cluster_state event type mismatch - Remove polling code (poll_interval, max_poll_workers, --poll-interval CLI) SDK changes: - Add NodeSnapshotEvent, HealthChangedEvent, AggregateEvent dataclasses - Add stream_node_events() method (async + sync) * fix: address review feedback on node event streams - Fix stop() to let SSE manager exit naturally instead of force-stopping the event loop (ensures finally cleanup runs) - Guard against empty/invalid SSE data from ping frames - Treat missing node_id as identity mismatch (409) when expected_node_id is provided - Fix stale docstring on _update_metrics
