phoxal-model

The canonical, validated Phoxal robot model, and the one document it is persisted as.

Robot is the whole of a compiled robot: its identity and structure, the motion it may make, the services it runs with their configuration, the components it mounts, and the component_types behind them with the simulation folded into each. robot.component(id) joins an instance with its type and simulation, so no consumer joins those maps by hand.

manifest::ManifestDocument wraps a Robot under the schema tag phoxal/manifest/v0. It lives here rather than in phoxal-bundle so the compiler that writes it and the reader that loads it both reach it through the crate that owns the body.

Authored project documents belong to phoxal-manifest. The bundle layout - where manifest.json sits and how its assets are read - belongs to phoxal-bundle. This crate owns no filesystem layout at all.
