dx: auto-sync home.md from readme.md via lint-staged

- Add .lintstagedrc.cjs with function syntax to run update-readme
  whenever README.md is committed, then auto-stage home.md
- Move lint-staged config out of package.json (functions require .cjs)
- Remove update-readme from postinstall (no longer needed there)
