fix(ci): pin third-party actions to full commit SHAs - #27
Conversation
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.

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.
