Cartography

This is one of those tools you install once and forget about until you need it, then you're glad it's there. It generates hierarchical codemaps of repositories and stores them in `.slim/cartography.json` at the root. The workflow is smart about not redoing work: it checks for existing state first and only reinitializes if needed. Most useful when you're dropped into an unfamiliar codebase or need to document structure for your team. With 377 installs and 4.6K stars on the parent repo, it's clearly solving a real problem. The step-by-step workflow in the docs suggests the author actually thought through the UX instead of just dumping output.
