Pull Request Overview

This PR refactors the trigger key detection system into modular observers, implements system window manager integration, and transitions several singletons to the shared pattern. The refactoring separates trigger key and middle-click detection logic into dedicated observer classes while maintaining the same functionality.

Key Changes:

• Modularized trigger key detection into dedicated observer classes
• Integrated system window manager padding settings dynamically
• Migrated multiple manager classes to the singleton pattern with shared instances

I've tested this locally for a while and reviewed the code. I can't see, feel, or notice any major issues between the new and old versions, so I'll accept this PR into the main.
