EcsRetargetProfile

Spec for ecs.RetargetProfile → the native RetargetProfile component. The canonical role→bone map that lets a clip authored on one rig drive this body through the shared role vocabulary.

A separate component from Skeleton: its presence on an entity is the gate that says "this rig participates in retargeting" (a humanoid today). A skeleton with no RetargetProfile is still a fully working skeleton — it plays clips authored on its own rig directly instead of joining the shared retarget pool.

Like every spec under ecs.components.<Name>, it describes one Rust component (public name, the Rust type it maps to, and the per-field entries the generic ecs verbs use to build and read values) and is registered by the ecs module to mint its typed constructor.
