Subject: [PATCH] ci: cover Debian 13 and Ubuntu 22.04 in the deb-install
 matrix

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.
