Add room deletion on agent session close

[toubatbrian]

Summary

• Add JobContext.deleteRoom() for deleting the current or specified LiveKit room.
• Add RoomInputOptions.deleteRoomOnClose, defaulting to false, and wire RoomIO to delete the room when the agent session closes.
• Preserve close-time behavior by capturing JobContext when RoomIO is created and awaiting the delete task during RoomIO teardown.

Test plan

• pnpm test agents/src/job.test.ts agents/src/voice/agent_session.test.ts agents/src/voice/room_io/room_io.test.ts
• pnpm build:agents
• Manually verified with examples/src/basic_agent.ts by enabling deleteRoomOnClose and confirming the room deletion completed on session close.
