Module graph 

Dependency graph construction and traversal algorithms.

This module implements the dependency graph that tracks relationships between files in the analyzed codebase. It provides:

• BFS traversal for finding all files affected by a change
• Topological sort for ordering reanalysis to respect dependencies
• Cycle detection during topological sort
• Bidirectional queries for both dependencies and dependents

Design Pattern

Adapted from ReCoco’s scope traversal (analyzer.rs:656-668) and is_op_scope_descendant ancestor chain traversal.

Structs

DependencyGraph

Enums

GraphError
