FixedMathSharp v5.0.2

Added

• Added FixedTransform, a mutable deterministic transform shell backed by Fixed4x4 for shared LSF host/runtime transform state.
• Added barycentric product helpers:
  • FixedMath.SumSquaredBarycentricProducts(...)
  • FixedMath.SumBarycentricProducts(...)
  • Fixed3x3.CreateBarycentricProductSums(...)

Fixed

• Fixed Fixed4x4.SetGlobalScale(...) so scale updates preserve translation and rotation instead of rebuilding from scale alone.

Validation

• Added focused tests for FixedTransform, barycentric product helpers, and scale mutation preservation.
