SHA pin first-party GitHub Actions#243

Conversation
Pins every actions/* and github/* uses: reference in .github/workflows to its commit SHA, with the human-readable version preserved in a trailing comment, matching the convention already used for third-party actions. Removes the supply-chain exposure left by floating @vn tags now that dependabot has a 3-day cooldown configured. Follows cli/cli#13491 (cli/cli) and cli/cli#13490.

With the 3-day dependabot cooldown configured for
github-actions, version-tag references give no real benefit (dependabot still opens PRs on patch releases) while leaving us exposed to tag-mutation supply chain attacks on first-party namespaces. SHA pinning is the more consistent and defensible posture.Verification
@vNrefs remain (grep -E 'uses: (actions|github)/[^@]+@v[0-9]' .github/workflows/*.ymlreturns empty).<sha> # vX.Y.Zpins and will bump both the SHA and the comment on the next patch release.Opened as a draft for review; mark ready when checks pass.
