🐞 Reduce drag event overhead

[manuthebyte]

#1001

tldr

• Prevents global drag monitoring from doing work unless snapping/restore/stash features are active.
• Stops repeated window-resolution attempts during non-window drags (e.g., games).
• Resets drag state on mouse up to avoid stale drag tracking.

Tests

• I have run my tests on my NMS instance, works as expected now and doesn't bug anymore.

This looks good, and it makes sense that this would cause lag. Thank you!
