Bryce 6feb83c9e3 Add pose retargeting pipeline ...

Single command that runs RTMPose3D inference on a reference image and
retargets the keypoints onto a Mixamo-named armature in a .blend file:

    ./pose.sh <reference.png> <input.blend> <output.blend>

Components:
- pose.sh: shell wrapper that runs RTMPose3D in the rtmpose3d conda env
  then invokes Blender headless with apply_pose.py.
- apply_pose.py: opens the input .blend, finds the character armature,
  applies pure FK direction-matching for arms and legs, captures head
  yaw via orient_bone with the horizontal ear axis, lands the rig on
  the floor, saves the posed scene, and renders a front-view preview.
- inputs/: test references (basepose, basepose2, 0102, pose-test, squat)
  and the rosella-hunyuan-online rig blend.
- README.md: usage, design notes, and the list of bones intentionally
  left at rest (head, feet, spine, clavicles).

mmpose is treated as an external library at $MMPOSE_DIR; this repo is
only the retargeting glue.
