feat(rah-light): remove voice features
- Delete voice hooks: useVoiceSession, useRealtimeVoiceClient, useAssistantTTS, useVoiceInterruption - Delete voice API routes: /api/voice/tts, /api/realtime/ephemeral-token - Delete voice service: src/services/voice/usageLogger.ts - Clean up RAHChat.tsx: remove voice stub hooks and voice-related state/handlers - Clean up TerminalInput.tsx: remove voice props, mic icons, amplitude visualizer Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

## Story 1: Remove agent delegation system
|

- Completed: Thu 29 Jan 2026

- Files modified:

- src/services/agents/workflowExecutor.ts (removed delegation streaming)

- Learnings:
|

- Delegation system was deeply integrated with workflows; had to refactor to direct execution
|
||||
- UI components that will be deleted later needed stub types to compile
|

- Voice hooks also needed stubs in RAHChat.tsx (will be cleaned up in Story 2)
