fix(ci): pin third-party actions to full commit SHAs

The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at
startup — startup_failure, no jobs, "this workflow graph cannot be shown" — so these workflows
could not run at all. This resolves each ref to the commit it currently points at and records the
ref in a trailing comment, e.g. actions/checkout@<sha> # v4.

dtolnay/rust-toolchain takes its toolchain from the ref itself, so those steps also gained an
explicit with: toolchain: input; without it, a SHA ref would silently lose the channel.

No behaviour is intended to change beyond the pins.

📝 Summary

Summary by CodeRabbit

  • Chores
    • Pinned GitHub Actions used across CI, security, validation, release, and deployment workflows to immutable commit references.
    • Retained version labels alongside pinned actions for easier maintenance and auditing.
    • Workflow steps and runtime behaviour remain unchanged.

Walkthrough

The pull request replaces mutable GitHub Actions version tags with immutable commit SHA references across 21 workflow files. Version comments remain where supplied. Workflow logic and action inputs are unchanged.

Changes

Workflow action pinning

Layer / File(s) Summary
Core workflow action pins
.github/workflows/boj-build.yml, .github/workflows/container-build.yml, .github/workflows/dogfood-gate.yml, .github/workflows/e2e.yml, .github/workflows/estate-rules.yml, .github/workflows/guix-policy.yml, .github/workflows/openssf-compliance.yml, .github/workflows/rhodibot.yml, .github/workflows/runtime-policy.yml, .github/workflows/security-policy.yml, .github/workflows/wellknown-enforcement.yml, .github/workflows/workflow-linter.yml
Checkout references now use commit SHAs instead of the v7.0.1 tag.
Analysis workflow action pins
.github/workflows/codeql.yml, .github/workflows/quality.yml, .github/workflows/proofs.yml, .github/workflows/sonarqube.yml, .github/workflows/static-analysis-gate.yml
Analysis, quality, proof, SonarQube, upload, download, and setup action references now use commit SHAs.
Pages and release action pins
.github/workflows/pages.yml, .github/workflows/release.yml
Pages and release action references now use commit SHAs. Version comments identify the corresponding action versions.
Automation and notification action pins
.github/workflows/dependabot-automerge.yml, .github/workflows/instant-sync.yml, .github/workflows/push-email-notify.yml
Dependabot metadata, repository dispatch, and SMTP notification action references now use commit SHAs.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 9db64

The workflow-linter job may fail because the CodeQL action lock entry was not regenerated. Update the lockfile before merging; also restore the version comment for the notification action pin.

Keep the original v0.3.0 ref in the trailing comment.

This line retains the NOSONAR note, but it does not identify the ref replaced by 22e7bdb322c430c1d0dac6b3bb307f4bb139d0be. Add v0.3.0 so reviewers can audit the pin without consulting another file.

Regenerate the lockfile for the CodeQL pin.

codeql.yml uses github/codeql-action at v4.38.0 with commit b96794f015dfd88f77b49b1c93e0fa7110f94c63, but actions.lock records v4.37.9 with commit cdf488f595d80d6e07e03d4674febd5ab45fa938. workflow-linter.yml runs gh actions-lock --verify-local, so this stale entry can fail lockfile verification. The SonarQube, quality, proofs, and static-analysis entries match their workflow pins.
