This commit addresses PR review comments by fixing the fundamental
type incompatibility between Rectangle (Array<number>) and strict
tuple types (Rect = [x, y, width, height]).
Key changes:
- Updated Rectangle class methods to accept both Rect and Rectangle unions
- Fixed all measure functions (containsRect, overlapBounding, etc.) to accept Rectangle
- Updated boundingRect interfaces to consistently use Rectangle instead of Rect
- Fixed all tests and Vue components to use Rectangle instead of array literals
- Resolved Point type conflicts between litegraph and pathRenderer modules
- Removed ReadOnlyPoint types and unified with Point arrays
The type system is now consistent: boundingRect properties return Rectangle
objects with full functionality, while Rect remains as a simple tuple type
for data interchange.
