Modularity

Canon: docs/modularity.md. Paths: agents-references.

Rules (summary): packages never import apps/mobile or features; no feature→feature imports (compose in app/router); package-owned contracts for cross-cutting; capabilities not concrete cubits; no vague Utils/Helper buckets.

Checks: bash tool/check_package_dependency_dag.sh; bash tool/check_feature_modularity_leaks.sh; route/DI → ./bin/router_feature_validate.
