Module graph_utils 

Graph utilities for cycle detection and traversal

This module provides shared utilities for call graph traversal, implementing TIGER-02 mitigation for circular import protection.

TIGER-02 Mitigation

Risk: Cycle detection in diff-impact call graph traversal Severity: Critical Mitigation: Implement visited set for call graph traversal. Use HashSet<(PathBuf, String)> to track (file, function) pairs. Abort with partial results if cycle detected.
