server/app.py
=============
Entry point for multi-mode deployment (uv run server / python -m server.app).

Loads the FastAPI app from the root-level server.py via importlib so the
`server` package name does not shadow the root module, and exposes a
main() function for the [project.scripts] console script entry point.
