"""Entry point del Runtime servidor.

Uso:
    uv run vms-runtime-server --vmsproj path/to/project.vmsproj
    uv run vms-runtime-server                  (genera proyecto demo y arranca)

Sin --vmsproj genera el proyecto demo de Sprint 0 y arranca el servidor
con simulator-driver para que puedas probar el cliente y la API.
