Testing Framework: Unit Tests

[Weisl]

• Operators: Create a complex test scene to cover all object types and data types to be renamed and test all of the Renaming operators with different settings
• Addon Registration & Unregistration: Ensure the addon initializes and cleans up correctly, with no lingering artifacts or errors and no unnecessary consolte prints.
• Blender Version Support: Verify that the addon functions correctly on all specified Blender versions (4.2LTS, 4.5LTS, 5.1LTS) - generally all current LTS versions + the most recent one without compatibility issues.
