Closing — this is a false positive, not a real action update.

`dtolnay/rust-toolchain@1.88` is not an action version pin: the tag selects the Rust toolchain to install. Bumping it to `1.100` would make the MSRV (1.88) job install Rust 1.100, silently defeating the very guard it exists to enforce.

It is also not installable — Rust 1.100.0 has not been released:

error: could not download nonexistent rust version `1.100.0-x86_64-unknown-linux-gnu`: … 404

dtolnay/rust-toolchain is now in the ignore list in .github/dependabot.yml; the pin stays manual and moves only when the declared MSRV in Cargo.toml moves.

dtolnay/rust-toolchain tags are Rust toolchain selectors, not action
releases — `@1.88` means "install Rust 1.88". Dependabot read that as a
version and opened #8 to bump it to 1.100, which would have made the
"MSRV (1.88)" job install a newer compiler and silently defeat the guard.
It could not even install: Rust 1.100.0 is unreleased, so the job 404'd.
