fix: WOM2 bone data in client renderer, WOM tests, docs update

- Fix WOM→M2Model conversion: copy boneWeights/boneIndices from WOM2
  vertices (was dropping skeletal binding data, breaking animation)
- Copy bone hierarchy and animation sequences from WOM2 to M2Model
  so animated WOM2 models render with proper skeletal deformation
- Add 3 WOM format tests: WOM1 binary structure, WOM2 magic check,
  invalid magic rejection (6 new assertions)
- CHANGELOG: document WOM1/WOM2 animated model support
- README: clarify WOM1 (static) vs WOM2 (animated) models
- 334 total assertions across 87 test cases
