Make lint and test phases of the Dockerfile (closes #96)

Follows the template: Dockerfile.lint is gone; the Dockerfile has a lint
phase (eslint, prettier --check .) and a test phase (vitest), and its last
stage compiles and depends on both. script/lint and script/test build one
phase each with --no-cache; script/docker and script/cibuild pass
--no-cache, so CHECK_EPOCH and LINT_EPOCH are removed. script/cibuild is
the single image build, so CI runs lint and the tests once each. The tests
that checked the old layout are deleted, REPO_POLICIES.md is re-copied and
the README describes the new layout.
