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

  • Security

    • Pinned workflow actions to immutable commit references, improving build reproducibility and reducing supply-chain risk.
    • Applied consistent action pinning across checkout, artifact, deployment, notification, analysis and policy workflows.
  • Release Automation

    • Added automated GitHub Release creation using changelog content.
    • Supports prerelease detection from tag names while keeping releases out of draft status.

Walkthrough

The pull request replaces mutable GitHub Actions tags with immutable commit SHAs across workflow files. It also adds a release job that publishes GitHub Releases using changelog output and detects prereleases from tag names.

Add pinned release publication

The workflow pins existing actions and adds a release job. The job uses changelog output, disables drafts and generated notes, and marks tags containing -rc, -beta, or -alpha as prereleases.

Merge Risk: 🟠 High · up to fd61f

Tag-triggered releases currently fail before publication because the workflow downloads a nonexistent git-cliff asset; release notes would also ignore the repository’s configured format after that is fixed.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Download the versioned git-cliff asset. The tag-triggered changelog job runs on ubuntu-latest x86_64, so the command requests git-cliff-x86_64-unknown-linux-gnu.tar.gz. The latest release provides git-cliff-2.14.1-x86_64-unknown-linux-gnu.tar.gz, so curl -f fails before changelog generation starts. Resolve the release version before constructing the asset URL, or use a supported installer that handles versioned assets.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Pass the repository Git Cliff configuration to both commands. The tag-triggered changelog job omits .machine_readable/configs/git-cliff/cliff.toml, which the repository’s release commands explicitly use. When these steps run, the generated release notes and CHANGELOG.md can differ from the repository’s configured format or content.

Restore the original tag comment.

The trailing comment does not identify the original v0.3.0 reference. This does not meet the PR requirement for readable pin provenance. Keep the NOSONAR justification, but add v0.3.0 to the comment.
