feat: Wyoming→OpenAI TTS bridge for Tomoko voice!

New approach: Use OpenClaw's native Discord voice + HTTP bridge

Added:
- bridge.py: OpenAI-compatible TTS proxy (OpenAI format → HA → Piper)
- test_bridge.py: Quick test script for bridge
- OPENCLAW_CONFIG.md: Instructions for OpenClaw config update

How it works:
1. OpenClaw calls bridge.py on localhost:8000/v1/audio/speech
2. Bridge converts to Home Assistant TTS endpoint
3. HA returns Tomoko's Piper TTS voice
4. OpenClaw plays in Discord voice channel!

MVP is REAL! We just need to configure OpenClaw! 💕
