Subject: [PATCH] fix(ci): pin third-party actions to full commit SHAs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.
