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 by CodeRabbit

  • Security
    • Pinned third-party workflow actions to immutable revisions, improving build and deployment supply-chain security.
    • Existing workflow behaviour, permissions, inputs, and action versions remain unchanged.

Walkthrough

The pull request replaces mutable GitHub Actions version tags with immutable commit SHAs across seven workflows. Existing version comments, inputs, permissions, step order, and workflow behaviour remain unchanged.

Merge Risk: 🔵 Low · up to ad616

The notification workflow remains operationally low risk, but its pinned action lacks the required v0.2.0 reference comment and should be corrected for traceability.

A rabbit checks each workflow line
And finds each action’s commit sign
The tags stay noted, neat and clear
The build hops on without a fear
Seven paths now hold their place
With steady pins in every case

Restore the original version comment.

Line 43 does not identify the retained v0.2.0 ref. This differs from the PR requirement for every pin. Add v0.2.0 to the existing trailing comment.
