"""Three Blocks — the hub addon (docs/plans/three-blocks-blender-addon.md).

The one Blender addon a user installs. It shares the sign-in credential with
the `three-blocks` CLI and owns the catalog, install, and runtime lifecycle for
managed tool-addons.

Ships with BOTH manifests: blender_manifest.toml makes it a 4.2+ extension,
this bl_info keeps legacy (pre-4.2) scripts/addons installs working.
