Missing dependency cache · CI
Add `Swatinem/rust-cache@v2` (the de-facto cargo cache), or an `actions/cache@v4` step keyed on `Cargo.lock`.

Add a `concurrency:` block keyed on branch to cancel superseded runs when devs push twice quickly.

No job sets `timeout-minutes`, so a hung step can run to GitHub's 6-hour default. Add `timeout-minutes` to each job.

macOS bills ~10× and Windows ~2× a Linux minute. The cost estimate above assumes Linux, so your real spend is higher. Move any job that doesn't need them to `ubuntu-latest`.

Runs on every push/PR with no `paths:` filter, so docs-only changes still trigger full CI. Add a `paths:` filter if that's common.
