chore: prep repo for public visibility

- untrack graphify-out/ (37 files): tooling artefacts that leaked the
  maintainer's local paths via .graphify_python and .graphify_root, plus
  token-cost data. Added to .gitignore; files stay on disk.
- commit build/skip-sign.js: package.json references it via
  win.signtoolOptions.sign, but build/ was gitignored, so
  npm run electron:build failed on a fresh clone. build/* stays ignored,
  only the stub is negated.
- CLAUDE.md: mark D:\Repos\claude-code-best-practice as a machine-local
  maintainer path that is not part of this repo.
