After cache restore, dpkg had no record of the installed packages because:
1. Only preinst/postinst scripts were cached from /var/lib/dpkg/info/,
missing .list, .md5sums, .conffiles, and other metadata files
2. The dpkg status database (/var/lib/dpkg/status) was never updated
This meant dpkg -s, apt list --installed, and anything checking package
state would not see the restored packages.
Fix:
- Cache all /var/lib/dpkg/info/<package>.* files (not just install scripts)
- Save each package's dpkg status entry to a .dpkg-status file
- On restore, append status entries to /var/lib/dpkg/status (skipping
packages that are already registered)
Adds tests verifying dpkg -s reports packages as installed after both
fresh install and cache restore.

Bring the integration tests from the separate cache-apt-pkgs-action-ci
repo into this repo. Tests now use `uses: ./` to test the local checkout
directly, eliminating the need for cross-repo dispatch events.
Tests cover:
- Core workflow: install, restore, cache invalidation, package ordering
- Error handling: empty packages, missing packages, invalid version
- Regression tests: issues #36, #37, #72, #76, #79, #81, #84, #89, #98, #106
- Special cases: multi-arch cache keys, virtual packages
Changes from the external CI tests:
- Uses `uses: ./` instead of `uses: awalsh128/cache-apt-pkgs-action@master`
- Updated checkout to actions/checkout@v4
- Made version-list assertions resilient (grep for expected packages
rather than exact string match, since dependency versions change
with Ubuntu updates)
- Improved error-case verification (check outcome != failure rather
than only running on failure)
- Triggers on push to master/dev/staging and on pull requests
