- Added support for new canvas node types: curves, color-adjust, light-adjust, detail-adjust, and render. - Implemented validation for adjustment nodes to restrict incoming edges to one. - Updated canvas connection validation to improve user feedback on invalid connections. - Enhanced node creation and rendering logic to accommodate new node types and their properties. - Refactored related components and utilities for better maintainability and performance.
