- Vector4.md: Add index mapping (0=x, 1=y, 2=z, 3=w) to operator[] description
- Transform.md: Add proper '运算符' subsection header for operator* documentation
Found and fixed missing operator documentation:
- Vector4: operator[] index mapping was undocumented
- Transform: operator* was listed without proper section header
- Updated box.md to clarify that Box uses OBB semantics for Contains
but currently uses AABB for Intersects(Box)
- Updated intersects-box.md to document that it uses AABB algorithm
instead of SAT, since the current implementation ignores transform
- Added notes explaining the current limitations of the Box implementation
