🟢 Approval recommended

The changes are targeted to CI/test expectations and workflow orchestration, with only a minor security hardening suggestion noted for the newly introduced action pinning.

Pull request overview

This PR addresses a CI coverage failure by updating Rust toolchain expectations and adjusting the coverage workflow to run sooner while keeping nightly pinned to a known-good date.

Changes:

• Updated UI test stderr snapshots to match current compiler diagnostics.
• Normalized Rust lint names in Cargo.toml (underscore form).
• Updated Rust nightly pin and made the coverage job depend on check (plus switched disk cleanup to an action).
