feat: auto-escalation system + agentic loop fixes (#149) (#149)

Wire up automatic error-to-task escalation and fix the agentic loop
stopping after the first tool call.

Auto-escalation:
- Add swarm.task_queue.models with create_task() bridge to existing
  task queue SQLite DB
- Add swarm.event_log with EventType enum, log_event(), and SQLite
  persistence + WebSocket broadcast
- Wire capture_error() into request logging middleware so unhandled
  HTTP exceptions auto-create [BUG] tasks with stack traces, git
  context, and push notifications (5-min dedup window)

Agentic loop (Round 11 Bug #1):
- Wrap agent_chat() in asyncio.to_thread() to stop blocking the
  event loop (fixes Discord heartbeat warnings)
- Enable Agno's native multi-turn tool chaining via show_tool_calls
  and tool_call_limit on the Agent config
- Strengthen multi-step continuation prompts with explicit examples
