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
    • GitHub Actions workflows now use immutable commit references for third-party actions instead of version tags.
    • Existing workflow versions and behaviour remain unchanged, improving build and automation reproducibility.

Walkthrough

GitHub Actions references across repository workflows now use fixed commit SHAs instead of version tags. Version comments remain where specified. Workflow inputs, triggers, permissions, and job logic are unchanged.

Correct the stale actions.lock hash in the audit comment.

The action uses 22e7bdb322c430c1d0dac6b3bb307f4bb139d0be, and .github/workflows/actions.lock records sha1-22e7bdb322c430c1d0dac6b3bb307f4bb139d0be. The trailing comment still records sha1-ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7. Update the comment so the audit metadata matches the pin authority.
