Add daemon E2E test for listAgents()

- Add E2E test that creates two agents, verifies both are returned by
  listAgents(), deletes one, and verifies only the remaining agent is
  returned
- Update listAgents() in DaemonClient to compute current agent list from
  session_state, agent_state, and agent_deleted messages in the queue
- Fix createAgent() to use skipQueueBefore option so second agent creation
  doesn't match stale messages from first agent
