Subject: [PATCH] Add in-repo action integration tests

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
