docs: mark backend hang bug as resolved

Backend POST /chat endpoint verified working 2025-11-01:
- Governor agent: ~20s response
- Finance agent: 17.5s response
- SEO agent: 28.3s response

Issue was already fixed with await getRawBody() pattern.
Previous "hanging" was normal Claude API latency (15-30s).

Testing: curl -X POST localhost:8791/chat -d '{"prompt":"test"}'
Result: Returns valid JSON response with agent output
