- Replace serde_yml with serde_norway (RUSTSEC-2025-0068: serde_yml is
unsound and archived; serde_norway is the recommended maintained fork)
- Remove unused toml dependency (was resolving to v1.1.2 which requires
edition2024/Rust 1.85, breaking the MSRV 1.80 check)
- Run cargo fmt to fix formatting diffs caught by lint job
- Fix cog commit check to use from_latest_tag so pre-conventional-commits
history does not cause the check to fail
- Remove semver job: dredge is a binary-only crate with no lib target,
cargo-semver-checks cannot check it
