Alex Dunmow cd88c808b0 initial: standalone check-safety module hoisted from CMS
Static safety/lint runner for the BlockNinja codebase. ~25 invariant
checks across Go and frontend sources. Was at git.dev.alexdunmow.com:block/ninja
in backend/cmd/check-safety/ until the 2026-06-06 consolidation moved
the BlockNinja repos under a shared ~/src/blockninja/ parent.

This repo is the standalone extraction:
- Own go.mod (git.dev.alexdunmow.com/block/check-safety, go 1.26.4)
- Vendored internal/{helpers,theme} from CMS (Go's internal/ rule
  blocks cross-module imports; vendoring is the workaround)
- CLI contract unchanged: `check-safety <target-dir> [--flags]`
- CMS Makefile shells into ../check-safety for safety-check /
  install-safety-checker targets
