FIX - RelativeCursorPosition Changed<> query filter

[chamaloriz]

Problem

This pseudocode was triggering constantly, even with the Changed<> query filter.

pub fn check_mouse_movement_system(
    relative_cursor_positions: Query< &RelativeCursorPosition, (Changed<RelativeCursorPosition>, With<Button>)>,
) {}

Solution

• Added a check to prevent updating the value if it hasn't changed.
