This update introduces a configurable TEST_PATTERN variable in the Makefile,
allowing selective execution of unit, integration, and E2E tests without
modifying scripts.
Key changes:
- Add TEST_PATTERN (default: test_*.py) to Makefile and export it.
- Inject TEST_PATTERN into all test containers via `-e TEST_PATTERN=...`.
- Update test-unit.sh, test-integration.sh, and test-e2e.sh to use
`-p "$TEST_PATTERN"` instead of a hardcoded pattern.
- Ensure flexible test selection via:
make test-e2e TEST_PATTERN=test_install_pkgmgr_shallow.py
This enables fast debugging, selective test runs, and better developer
experience while keeping full compatibility with CI defaults.
