ci: pin actions to commit SHAs and lint workflows - #6

Conversation
Every third-party `uses:` now carries a full commit SHA with a version comment, the form Dependabot reads to keep the pins fresh. lean-update's `dev` and the shared ci-workflows actions on `main` are branch refs with no tag to pin to; `.github/pinact.yaml` exempts them and `.github/zizmor.yml` gives them a ref-pin policy. A `lints` job calls ci-workflows' lint-workflows action (actionlint, shellcheck over composite action scripts, pinact check and verify, zizmor). Getting zizmor clean: every checkout sets `persist-credentials: false` (lean-update pushes through its own token input, not the checkout's git credentials), the Nix installer reads `github.token`, and Dependabot gets the 7-day cooldown zizmor requires.
