Synchronise .github/workflows/actions.lock with the workflow pins.
.github/workflows/actions.lock is the declared pin authority. Regenerate it with gh actions-lock so it records these current references:
github/codeql-action@v4.38.0→sha1-b96794f015dfd88f77b49b1c93e0fa7110f94c63hyperpolymath/cicd-suite@main→sha1-180b419825d238f8b606584c970a81dfa7cb6f81actions/deploy-pages@v5.0.1→sha1-368f82528645a54fb793d4d04e342629a3f51346hyperpolymath/smtp-notify-action@v0.3.0→sha1-22e7bdb322c430c1d0dac6b3bb307f4bb139d0be
Update the smtp pin-authority comment to use the new lockfile SHA. Do not edit the generated lockfile by hand.

…0.1.6) `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.

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 workflowscould 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-toolchaintakes its toolchain from the ref itself, so those steps also gained anexplicit
with: toolchain:input; without it, a SHA ref would silently lose the channel.No behaviour is intended to change beyond the pins.
