SugiyamaLayout class

Sugiyama-style hierarchical graph layout algorithm

This layout algorithm is suitable for directed graphs (DAGs) and produces a layered layout similar to what Mermaid.js uses. The algorithm consists of these phases:

1. Cycle removal (make the graph acyclic)
2. Layer assignment (assign nodes to horizontal/vertical layers)
3. Crossing reduction (minimize edge crossings within layers)
4. Coordinate assignment (position nodes within layers)
