1//! Render a loaded compose into on-disk artifacts.
2//!
3//! Outputs under `<root>/state/`:
4//! - `envs/<project>-<agent>.env`      — env vars for the agent wrapper.
5//! - `mcp/<project>-<agent>.json`      — MCP stdio config for the runtime.
6//!
7//! `systemd` / `launchd` unit rendering lives behind a feature flag when
8//! those back-ends are enabled via `supervisor.type`.
