Pins every actions/* and github/* uses: reference in .github/workflows to its commit SHA within its current major version, preserving the human-readable version in a trailing comment. Improves supply-chain posture against tag-mutation attacks on first-party namespaces. Follows cli/cli#13491 (cli/cli) and cli/cli#13490.

actions/checkoutee0669bd1cc54295c223e0bb666b733df41de1c5 # v2.7.0actions/setup-gobfdd3570ce990073878bf10f6b2d79082de49492 # v2.2.0Why
SHA pinning protects against tag-mutation supply chain attacks on first-party action namespaces. While the cli/cli#13490 dependabot-cooldown framing doesn't apply here (this repo has no
dependabot.yml), the security improvement stands on its own.Notes / follow-ups
actions/checkout@v4+,actions/setup-go@v5+) is intentionally out of scope for this PR.dependabot.yml. Adding one would let dependabot automatically bump these SHA pins (and Go modules). Worth considering as a follow-up.Verification
@vN(tag-only) refs remain.Opened as a draft for review; mark ready when checks pass.
