Upgrades WOM from geometry-only (WOM1) to fully animated (WOM2): - WOM2 magic (0x324D4F57) for animated models, WOM1 for static - Vertex extended: +boneWeights[4] +boneIndices[4] (40 bytes vs 32) - Bone data: keyBoneId, parentBone, pivot, flags per bone - Animation data: per-sequence per-bone keyframes with translation, rotation (quaternion), scale at millisecond timestamps - fromM2() now preserves all skeletal data: bone hierarchy, weights, and per-sequence keyframes from M2 animation tracks - Backward compatible: WOM1 files load without bone data (32-byte vertices read and padded with default bone weights) - FORMAT_SPEC.md updated with WOM2 binary layout
