com.unity.splines@2.8.1

## [2.8.1] - 2025-03-28

### Bug Fixes
- [SPLB-345] Fixed a bug which was causing null reference exceptions during shutdown in IL2CPP builds.
- [SPLB-337] Fixed a bug where `JoinSplinesOnKnots` would throw a null reference exception when one of the splines was linked with another spline.
- [SPLB-341] Fixed a bug where changing the tangent mode on a knot on a prefab would not persist when entering play mode.

### Changed
- Internal code cleanup to align with release standards.
