Rewrites the outdated README to accurately reflect the current state of the
project: corrects framework references (Quart/Hypercorn instead of Flask/Gunicorn),
documents all major features (autonomous AI conversations, multi-model LLM support,
WebSocket communication, Microsoft SSO, theme extraction), updates the project
structure and tech stack, adds architecture overview, environment configuration
table, and deployment instructions using deploy.sh/systemd.
