This PR optimizes the updateCurveMenuItems method in PathControlPointVisualiser.cs.

💡 What:

  1. Moved the calculation of totalCount (the number of selected control points) outside the foreach loop, as its value does not change during the iteration over menu items.
  2. Substituted the LINQ chain Pieces.Where(p => p.IsSelected.Value).Count(p => p.ControlPoint.Type == item.PathType) with a more efficient single call to Pieces.Count(p => p.IsSelected.Value && p.ControlPoint.Type == item.PathType).

🎯 Why:

  • The original code was unnecessarily re-calculating totalCount for every menu item.
  • The Where().Count() pattern creates an intermediate IEnumerable allocation, whereas the single Count() call with a combined predicate avoids this overhead.

📊 Measured Improvement:
While full benchmarks in this environment timed out due to the project's scale, this is a textbook LINQ optimization that reduces GC pressure by eliminating intermediate allocations and improves CPU efficiency by hoisting loop-invariant code. In a UI-driven context like the slider editor context menu, this contributes to a smoother and more responsive experience.

- Move totalCount calculation outside the loop as it is invariant.
- Replace Where(predicate).Count(predicate) with a single Count(predicate) to reduce allocations.
