Add installer GUI and file system access feature

This commit introduces a new Tkinter-based GUI installer script (`installer/main.py`) that manages file extraction and shortcut creation. Additionally, a new file system access feature was added to the `ToolboxWindow` class, allowing users to open directories with platform-specific commands. Improvements also include platform-specific adjustments for Windows executables in the CMake configuration.
