Summary

Pin every uses: ref in .github/workflows/ (and any composite action
files) to a full 40-character commit SHA, with the original tag
preserved as a # vX comment.

Why

Tags and branches are mutable, so a compromised action can replace what
runs in our pipelines without changing the tag we reference. Pinning to
a SHA closes that supply-chain vector. See GitHub's hardening guide:
https://docs.github.com/en/actions/security-guides/security-hardening-for-github-actions#using-third-party-actions.

Deadline

TechOps is enforcing SHA-pinned GitHub Actions across the org.
Merging this PR brings the repo into compliance; workflows that still
reference mutable tags or branches may be blocked from running.

How

Generated mechanically with pinact run.
No version bumps were applied (strict pin); follow-up upgrades can come
from Renovate or a separate pinact run -u PR.

Test plan

  • CI green on this branch

Note

Low Risk
Workflow-only supply-chain hardening with no application or deployment logic changes; main risk is a mistyped SHA breaking CI until corrected.

Overview
Replaces mutable tag refs (@v2, @v1, etc.) on every third-party and MetaMask workflow step with immutable 40-character commit SHAs, keeping the original version in an inline # vX comment for readability.

Coverage spans build/lint/test, create release PR, and publish release workflows—actions/checkout, setup-node, cache, upload-artifact, and the MetaMask release actions. Runtime behavior of the jobs is unchanged; only which exact action revision runs is fixed.

Pin every `uses:` ref in .github/workflows and composite actions to a
full 40-character commit SHA, with the original tag preserved as a
comment, e.g.

    uses: actions/checkout@11bd719 # v4

Tags and branches are mutable; commit SHAs are not. Pinning to a SHA
closes a supply-chain vector where a compromised action could replace
what runs in CI without changing the tag we reference.

Generated mechanically with `pinact run`
(https://github.com/suzuki-shunsuke/pinact). No version bumps were
applied (strict pin).
