feat: cluster mode with leader election & WebSocket worker mesh#59
Conversation
Adds FlowcoreDataPumpCluster for HA failover and horizontal scaling of event processing. Leader fetches events and distributes to workers via persistent WebSocket connections. Uses abstract coordinator interface (user-implemented against their DB) for lease-based leader election and instance discovery. Falls back to local processing when no workers available.

Replace Deno-specific Deno.serve/upgradeWebSocket with a public handleConnection(ws: WebSocket) method. Users wire up their own HTTP server and call handleConnection on upgrade. Works with both Deno and Node.js (via ws package). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
