/**
 * gait — skeletal locomotion poses for the native character renderer.
 *
 * Fills the gap the render audit flagged: `LocomotionTrait` moves a node's root position, but
 * nothing maps movement to a *skinned walk cycle*. These pure functions produce an `AvatarPose`
 * (per-bone local rotations over a phase clock) that `CharacterHost` feeds to GPU skinning, so
 * the body actually strides. Modes line up with the real `LocomotionConfig.mode` vocabulary
 * (walk/run + an idle rest state); `speed` scales cadence.
 *
 * Bind pose is a T-pose (arms out along ±X), so each gait first brings the arms down to a
 * natural rest, then swings limbs about X for the stride. Pure math, no GPU.
 *
