- Extract MakePoint/AxisBounds/CrossAxisBounds helpers in CutOff to
eliminate repeated axis-dependent branching
- Simplify BuildProgram loop from 4 code paths to 2
- Use static EmptyExclusions to avoid per-part list allocations
- Fix double event subscription in ActionCutOff constructor
- Dispose debounce timer in DisconnectEvents
- Remove redundant BuildPerimeterCache call in OnMouseDown
- Extract TotalCutLength test helper, remove duplicate test

Replace CutOff.BuildPerimeterCache (List<Shape>) with Plate.BuildPerimeterCache
(Dictionary<Part, Entity>) throughout. Consolidate two Regenerate overloads into
a single method with optional cache parameter. Fix Shape intersection bug where
non-intersecting entities added spurious Vector.Zero points to results.

CutOff computes cut segments along a vertical or horizontal axis,
excluding zones around existing parts with configurable clearance.
CutOffSettings controls part clearance, overtravel, minimum segment
length, and cut direction (toward/away from origin).
