Refactor HWND management and modularize initialization

Centralized HWND handling into a dedicated `hwnd_module` for improved clarity and modularity. Updated `toolboxWindow` and `optionWindow` to use the new module abstraction. Adjusted related initialization code for better structure and maintainability.
