Addresses review feedback from #54 requesting unit test coverage for the Lifecycle service class.

Changes

• Add tests/unit/services/test_lifecycle.py with tests covering:
  • _get_prime_dirs_from_project() helper function (partition-to-package name mapping)
  • Lifecycle.get_prime_dir() method (including error handling for non-existent packages)
  • Lifecycle.prime_dirs property

Test Coverage

# Tests verify partition prefix stripping works correctly
project_info.prime_dirs = {
    "package/my-package": Path("/work/partitions/package/my-package/prime"),
}
result = _get_prime_dirs_from_project(project_info)
# Returns: {None: default_prime, "my-package": package_prime}

Tests also verify:

• Non-package partitions are ignored
• Empty partition keys are handled
• DebcraftError is raised for non-existent package lookups

Pull request overview

This PR adds comprehensive unit tests for the Lifecycle service class, addressing review feedback from PR #54. The tests validate partition-to-package name mapping logic and directory retrieval methods.

• Adds tests/unit/services/test_lifecycle.py with tests for the helper function _get_prime_dirs_from_project(), the get_prime_dir() method, and the prime_dirs property
• Tests cover edge cases including partition prefix stripping, non-package partition filtering, empty partition handling, and error handling for non-existent packages
• All tests use proper mocking and follow the repository's established testing patterns

I'm unable to rebase this branch. My environment doesn't support git rebase operations since force push is not available. Could you please perform the rebase manually, or alternatively, I can recreate the changes on a fresh branch based on main if that would help.

@copilot merge main into this branch and fix the conflicts.

Merged main into this branch and resolved conflicts in commit 4ea7627. All conflicts were resolved by accepting the main branch version (which contains PR #54), while keeping the lifecycle test file from this branch.
