`run()` now reparses imports and re-walks the AST once per configured `--project-packages` entry (each `ImportTracker.visit()` + `InheritanceVisitor.visit()`), which makes runtime scale linearly with the number of packages. Consider changing `ImportTracker` to accept a set of project packages and classify `internal` when `source_module in project_packages`, so the file is visited only once.
