**feat(release): adjust highest-tag detection tests and improve logging**

* Add debug output for latest vs current version tag in release git ops
* Treat “no version tags yet” as highest by definition
* Align unit tests with current *string-based* `tag >= latest` behavior
* Make tag listing mocks less brittle by matching command patterns
* Rename release init test to `test_init.py` for consistent discovery
