Add FlowRunner - execution bridge for BloxServer flows
FlowRunner connects Flow domain model to xml-pipeline's StreamPump:
- Lifecycle management: start(), stop() with state tracking
- Flow → OrganismConfig conversion: nodes become listeners
- Trigger handling: webhook, schedule, manual triggers
- Message injection: inject() to specific nodes, trigger() by trigger ID
- Execution tracking: events log, status reporting, message counting
States: CREATED → STARTING → RUNNING → STOPPING → STOPPED (or ERROR)
Usage:
runner = FlowRunner(flow)
await runner.start()
thread_id = await runner.trigger("webhook_id", payload)
await runner.stop()
Known limitation: Tool nodes need adapter wrappers to convert
@tool decorator (ToolResult) to handler pattern (HandlerResponse).
