"""
Cross-Repo Dependency Graph Builder
Scans repos for import/require/reference patterns and builds a directed
dependency graph. Detects circular dependencies. Outputs DOT and Mermaid.
Usage:
python3 scripts/dependency_graph.py /path/to/repos/
python3 scripts/dependency_graph.py --repos repo1,repo2,repo3 --format mermaid
python3 scripts/dependency_graph.py --repos-dir /path/to/ --format dot --output deps.dot
Patterns detected:
- Python: import X, from X import Y
- JavaScript: require("X"), import ... from "X"
- Go: import "X"
- Ansible: include_role, import_role
- Docker/Compose: image: X, depends_on
- Config references: repo-name in YAML/TOML/JSON
