🧪 test: improve coverage for name_from_url

[bashandbone]

🎯 What: The missing error path and general happy path tests for name_from_url in src/utilities.rs were addressed.
📊 Coverage: The scenarios now tested include an empty URL (error path), typical valid URLs with or without trailing slashes, and with .git extensions.
✨ Result: Test coverage improved, preventing future regressions to this pure string manipulation function.
