rust-code-smell

@mozilla-services

Runs clippy, cargo audit, and all relevant multi-backend Makefile targets for files changed in the current branch. Detects code smells, anti-patterns specific to this codebase, and surfaces issues across every affected backend before CI catches them. Also handles dependency-update verification (Cargo.toml / Cargo.lock changes from dependabot or manual bumps) via the `deps` mode.
