Pull request overview

This PR mutes (deafens) the AI agent by default during its initial introduction and unmutes it once the agent is ready for player input.

Changes:

• Add source-aware muting to distinguish system vs manual mute, and initialize system mute on room start.
• Introduce an onReadyForPlayerInput callback from the agent session to the game room/session to release the system mute.
• Update some story prompt text and widen the PeerTile max width.
