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.

`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.

📝 Summary

Summary by CodeRabbit

  • Security
    • Pinned workflow actions to immutable commit references instead of mutable version tags.
    • Improved the reproducibility and supply-chain security of automated builds, checks, deployments, releases, and notifications.
    • Workflow logic, permissions, triggers, and user-visible behaviour remain unchanged.

Walkthrough

This change replaces mutable GitHub Actions version tags with immutable commit SHAs across repository workflows. Version comments remain on the references. Workflow logic, permissions, triggers, inputs, and job structure remain unchanged.

Changes

Workflow action pinning

The notification action remains correctly pinned, but stale provenance text can mislead maintainers and pin audits; the PR is otherwise mergeable with a small follow-up.

Explanation

The description explains the purpose and intended behaviour, but it does not follow the repository template. It omits the required Summary, Changes, RSR Quality Checklist, Testing, and Screenshots sections.

Resolution

Restructure the description using the repository template. Add the required headings, list the key workflow and Rust toolchain changes, complete the RSR Quality Checklist, document the testing performed, and state whether screenshots or terminal output are applicable.

A rabbit checks each workflow line,
And pins each action neat and fine.
No floating tags can hop away,
Version notes still mark the day.
The burrow builds the same old way.

Correct the stale pin comment. .github/workflows/actions.lock already maps hyperpolymath/smtp-notify-action@v0.3.0 to sha1-22e7bdb322c430c1d0dac6b3bb307f4bb139d0be, which matches the workflow pin. Do not change the SHA. Replace the stale sha1-ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7 text and add the # v0.3.0 release label.
