⏳ Loading Screen — Visual Feedback (FIXED)

Issue
Some users could double-click actions, triggering a flaw in the legacy logic that resulted in an infinite loading screen.

Solution
The loading overlay was fully rebuilt with a modern, high-definition, symmetrical layout.
Long-running tasks are now offloaded to background threads, keeping the UI responsive at all times.
The window can also be closed safely using the X button.

Result
If you prefer not to wait—or if something goes wrong—you can simply close the loading screen without locking the application.

❌ Error Screen — Visual Feedback (NEW)

Issue
Console errors were not easily readable or copyable, making debugging and reporting difficult.

Solution
A dedicated error screen was introduced, allowing full error output to be viewed, copied, and dismissed cleanly.

Result
Errors can now be copied directly and shared via Discord or submitted as a GitHub issue for faster troubleshooting.
