ci: split CI into per-concern reusable workflows behind one ci-passed gate

Add uv lock --check, a wheel install smoke test, a PyInstaller dry run,
actionlint and zizmor on the workflows, CodeQL, and Dependabot for action
pins, uv, Go and npm dependencies. Release caches are disabled so zizmor's
cache-poisoning audit passes.
