style(workflows): stamp uses: comments with (YYYY-MM-DD)

Backfill the new canonical `# <tag-or-branch> (YYYY-MM-DD)` staleness
comment format on every existing SHA-pinned `uses:` line. The date
stamp is enforced by the new workflow-uses-comment-guard hook
(socket-wheelhouse template); without this pass every subsequent
workflow edit would have to fix surrounding stamps too.

Conservative rewrite: only touches lines whose existing `# <label>`
comment lacks a parenthesized date. Lines with no comment at all are
left for the hook to surface on next edit.

Today is the stamp date — these are pin SHAs as of 2026-05-15.
