The last of three oxfmt PRs, after #356 (the tooling) and #357 (the reformat).

• Gate. just fmt-check joins just ci, and CI runs the same two checks (oxfmt --check and scripts/fmt_templates.py --check) on the primary job, after the JavaScript lint step. Both run before the step fails, so every unformatted file is listed.
• Blame. .git-blame-ignore-revs names (Claude) Reformat JS, CSS, JSON and YAML with oxfmt #357's commit. GitHub's blame view reads it on its own; locally, git config blame.ignoreRevsFile .git-blame-ignore-revs turns it on. On minimal_dag.js (2320 lines), the lines blamed on the reformat go from 2255 to 243; the rest are lines the reformat created (split lines and the like), which git can't map back to older ones.
• Docs. CONTRIBUTING's formatting section says the check is gated, to run just fmt-js before committing, and how to set up blame.

Checked: the step's commands, run with a badly formatted line in a plain JS file and in a Jinja template file, fail in each case and pass on the clean tree; just ci passes.
