build: align scripts and workflows with actions/* convention

Match the standard layout used by actions/checkout, actions/setup-node,
etc.:

- package.json scripts: split format/format-check (Prettier) from
  lint/lint:fix (ESLint), and have pre-checkin run all four (format,
  lint:fix, build, test) in that order.
- validate.yml lint job runs format-check + lint as separate steps.
- test.yml drops the redundant --coverage flag (now in the test script).
- Drop dependabot-build.yml: actions/* don't auto-rebuild dist on
  dependabot PRs; the check-dist style validate / build job catches
  drift and a maintainer rebuilds locally if needed.
