FixedMathSharp v3.0.0

• Breaking Changes
  • Removed float-based numeric/vector overloads to enforce deterministic usage across Vector2d and Vector3d.
  • Core precision API refactor:
    • Fixed64.Precision replaced with Fixed64.MinIncrement.
    • Default epsilon/tolerance semantics were redefined (FixedMath.DEFAULT_TOLERANCE_L / Fixed64.Epsilon), which can change fuzzy-comparison behavior.
• Added
  • FixedMath.InvertedPI constant.
  • New Vector3d.SnapSmallComponentsToZero(...) helper for zeroing tiny components under a threshold.
• Changed
  • Degree/radian conversion paths in trigonometry moved to fixed-point math paths for deterministic consistency.
  • Vector epsilon guards improved across vector/component comparison logic.
• Fixed
  • Hardened Fixed64 scalar multiply/divide operator behavior, including improved 128-bit intermediate rounding/saturation handling.
  • Quaternion math corrections:
    • Euler conversion alignment (YXZ order consistency).
    • Rotation extraction stabilization (including matrix-based paths).
  • Additional Fixed64 operator corrections from #48.
• Maintenance
  • Project/test setup cleanup and release metadata housekeeping commits.
• Migration Notes
  • Replace uses of Fixed64.Precision with Fixed64.MinIncrement.
  • Remove/update any call sites relying on removed float overloads.
  • Re-validate tolerance-sensitive tests/simulations due to epsilon behavior changes.
