GridMind-RL server entry point.
The core simulation runs as a Go binary (main.go) on port 7860.
This module provides the Python entry point expected by OpenEnv spec
and pyproject.toml [project.scripts].
In Docker: the Go binary is started by supervisord.
For local dev: use `go run main.go` directly.
