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 the reliability and security of automated builds, scans, deployments, mirroring, and notifications.
    • Updated the Rust mirroring workflow to use the Rust master toolchain.

Workflow action pinning

Layer / File(s) Summary
Analysis and scanning workflow pins
.github/workflows/codeql.yml, .github/workflows/hypatia-scan.yml, .github/workflows/secret-scanner.yml
CodeQL, Hypatia, TruffleHog, and Gitleaks action references now use immutable commit SHAs.
Mirror workflow pins
.github/workflows/mirror.yml
Mirror jobs now pin checkout and SSH agent actions. The Radicle job pins the Rust toolchain action and selects master explicitly.
Publication and notification pins
.github/workflows/pages.yml, .github/workflows/push-email-notify.yml
Pages and email notification action references now use immutable commit SHAs.

The mirror workflow may fail to start, blocking repository mirroring, while several action pins are inconsistent with their authoritative lockfile. Fix both before merging.

Regenerate .github/workflows/actions.lock for the selected releases.

The workflow pins do not match the generated lockfile. The mismatches are CodeQL v4.38.0 versus v4.37.7, TruffleHog v3.97.5 versus v3.97.0, Deploy Pages v5.0.1 versus v5.0.0, and the SMTP action pin versus the lockfile’s v0.2.0 entry. If these releases are intended, run gh actions-lock; otherwise restore the locked releases.

Remove the added with mapping.

The parent step selects stable. This change adds a second with mapping with master while pinning the action. Duplicate mapping keys are invalid YAML, and retaining master would change the installed Rust toolchain. Remove the added mapping and keep toolchain: stable.

`actions.lock` is authoritative: the workflows carry readable refs and the lock records the
commit each ref resolves to, which is what actually runs. Refs that stop matching the manifest
make the whole repository unstartable — `startup_failure`, "Invalid lockfile".

Regenerated with the official extension (`github/gh-actions-lock`). The hand-pinned SHA refs are
reverted to their readable form here precisely because the lockfile, not the workflow, is what
pins them.
