Interface IRenderLayer

Represents a rendering layer in the graph canvas. Layers control Z-ordering and transform behavior for groups of elements.

Inspired by:

react-diagrams: Multiple layer types (LinkLayer, NodeLayer) with transform flags
Konva.js: Stage → Layer → Group → Shape hierarchy
Photoshop/Figma: Layer-based compositing model
