Based on the changes, I can see this is a significant feature addition that adds the ability to create agents and communicate with them through both text and audio, with a modal UI for agent creation and mode switching.

```
feat: add agent creation modal and agent-specific messaging

- Add CreateAgentModal component for creating new agents with mode selection
- Implement agent-specific text and audio message routing
- Add mode selector modal with visual mode switching UI
- Introduce unified stream reducer pattern for agent activity
- Refactor AgentStreamView to use StreamItem[] instead of raw notifications
- Update ActiveProcesses to show orchestrator pill and support mode switching
- Add message types: send_agent_message, send_agent_audio, create_agent_request, set_agent_mode
- Implement agent audio transcription and message forwarding in session handler
- Add mode badge UI showing current agent mode
- Update tmux capture-pane to allowed commands
