📝 README Overhaul ‑ Review Summary

Great work tightening up the SDK README! The new structure, badges and modernised examples substantially improve developer onboarding.

✅ What Looks Good

Area	Observation
Organisation	Clear intro, badges, and logical TOC
Installation	Accurate pip, Poetry and UV commands
Usage Examples	Sync & async patterns shown with practical Pydantic model
Streaming Docs	Concise SSE explanation with context manager

💡 Minor Suggestions (non-blocking)

1. Add from pydantic import BaseModel before declaring class RoomDescription for zero-friction copy-paste.
2. Consider showing export OPPER_API_KEY=... rather than embedding the key in code for best practice.

No blocking issues detected. Approving.
