fix: auto-load .env in state.py so dotenv works without explicit load_dotenv call

When running plain `python script.py` or bare uvicorn, .env is never
loaded automatically. Added a dotenv bootstrap block at the top of
state.py that finds and loads the nearest .env file (walks up from
models/ to the project root). Uses load_dotenv with override=False so
explicitly set environment variables always win over .env values.
Gracefully skips if python-dotenv is not installed.
