Adds two new gates to the existing format/lint/test/audit pipeline
(Makefile.toml `cargo make ci`, .forgejo/workflows/ci.yml):
- Cognitive complexity via clippy's nursery cognitive_complexity lint
(clippy.toml, threshold 15), scoped to --bins so test code's naturally
higher branch count doesn't get gated. Went with this over the closest
real cyclomatic-complexity tool (rust-code-analysis-cli) because that
crate hasn't shipped a release since Jan 2023.
- Test coverage via cargo-llvm-cov, chosen over cargo-tarpaulin for
friendlier behavior in containerized/dind CI (no ptrace). Report-only
for now (no --fail-under-lines) since a real threshold needs real usage
data first — see below. main.rs is excluded: it's orchestration glue
exercised by the real end-to-end `cargo run`, not unit tests.
Getting both gates running required writing pkgwatch's first tests
(previously zero). To make the GitHub-facing modules unit-testable
without hitting real github.com/api.github.com, added `GithubEndpoints`
(src/github.rs) so checker/fetcher/verifier take injectable base URLs,
and added mockito + tempfile as dev-dependencies. Result: 27 tests,
94% region / 96% line coverage excluding main.rs.
Also: cargo audit (now wired into `cargo make ci`) immediately caught a
real, currently-open advisory (RUSTSEC-2026-0285, published days ago) in
the transitive rustls dependency — bumped 0.23.44 -> 0.23.45 to clear it.
