+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 --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
