The GitHub deb-install matrix ran debian12/ubuntu24/ubuntu26, but the
local harness (testing/deb-install/test.sh) runs five distros. Add the
missing debian13 (trixie) and ubuntu22 legs so the cloud gate covers the
same distro set as local CI. Each new leg invokes the existing test.sh
scenario, so per-distro behavior is identical to the local run.
Update the granularity-only parity notes in ci.yml, ci-local.sh, and
check-ci-parity.sh to list the full distro set.
Bring the local runner (testing/ci-local.sh) and GitHub CI into agreement
on two axes.
Suite coverage: the admission-cap integration suite ran only locally, so a
regression in it could never turn the GitHub gate red. Add an admission-cap
leg to the integration matrix, add testing/check-ci-parity.sh (wired as
'ci-local.sh --check-parity') to diff the two suite sets and fail on
unexpected drift, and document the deliberate local-only (live-Tor) and
granularity-only differences in a comment block atop both runners.
Toolchain selection: every CI and packaging job installed its toolchain
with dtolnay/rust-toolchain@stable, but the rust-toolchain.toml channel pin
overrode it for all compilation, wasting an install and printing a
misleading rustc version. Switch the stable call sites to
actions-rust-lang/setup-rust-toolchain, which reads rust-toolchain.toml as
the single source of truth. Keep the explicit cache steps (cache: false on
the new action), set rustflags empty so the action does not impose a global
-D warnings the previous setup never applied, fold the macOS cross-compile
target into the action input, and leave the OpenWrt nightly Tier-3 leg on
dtolnay/rust-toolchain@nightly.
