Extend 'pkgmgr version' command with multi-source version detection (pyproject, flake, PKGBUILD, debian, spec, AnsibleGalaxy), implement SemVer parsing, consistency warnings, full E2E + unit test coverage.

"""
Unit tests for the pkgmgr CLI (version command).
These tests focus on the 'version' subcommand and its interaction with:
- git tags (SemVer),
- pyproject.toml version,
- and the mismatch warning logic.
Important:
- Uses only the Python standard library unittest framework.
- Does not use pytest.
- Does not rely on a real git repository or real config files.
