"""FastAPI app for the opencode_env MCP server.
Mirrors the standard OpenEnv pattern (echo_env / repl_env / jupyter_agent)
plus the custom Gradio UI mounted at ``/web`` per the
``customizing-web-ui`` doc.
Usage::
# Local dev:
E2B_API_KEY=... uvicorn server.app:app --host 0.0.0.0 --port 8000
# Docker:
docker run -p 8000:8000 -e E2B_API_KEY=... opencode-env
# HF Space: deploys via the root ``Dockerfile``.
The ``ENABLE_WEB_INTERFACE`` env var is set to ``true`` automatically so
the UI is always reachable at ``/web``. Set it to ``false`` to disable.
