sane.mk

Understands and extends the sane.mk GNU Make framework for shared deps, check, build, test, dist, debug, and system workflows. Detect a sane.mk repo by `include $(SANE_MK_ROOT)/...` in the Makefile or a generated `Makefile.lazy` with `SANE_*` variables. Use when: * editing this repo * adding Make targets/includes * wiring behavior through `SANE_*` variables * adopting sane.mk in another project * debugging why a target is not reachable * validating, linting, formatting, or testing in a sane.mk repo (the entrypoint is `make check` / `make test`, never direct tool calls) * editing any non-Make file in a sane.mk repo when you need to validate it
