README Excerpt

**diffctx selects the minimum code an LLM needs to review a git diff.** Instead of pasting whole files, it walks the dependency graph outward from the changed lines and stops once more context stops paying for itself. > Formerly published as `treemapper` — every command, flag, and API call works unchanged.
