Malabah Hub

--[[ 
    Combined Script:

    PART 1 - OVERLAY:
      A full-screen black overlay appears with rainbow-cycling text 
      ("made by Donm2091/donm21712") in its center. This overlay’s ZIndex
      is set high so that it appears on top of everything. After 3 seconds, 
      the overlay fades out and is destroyed.
    
    PART 2 - MAIN UI:
      A draggable UI panel (default windowed size 700×400) appears beneath.
      It contains:
         • Title: "Malabah HUB"
         • Fullscreen toggle button ("F") to switch between windowed and fullscreen modes.
         • Hide button ("-") that animates the UI closing (collapses vertically) and sends a notification.
         • X button ("X") placed immediately to the right of the hide button; when pressed, it destroys the entire UI.
         • An internal center notification stating:
             "this Script Containts MOST keyless Exploits! Enjoy."  
             (fades out after 5 seconds)
         • A top notification with rainbow text stating:
             "made by Donm2091/donm21712"  
             (fades out after 4 seconds)
         • If on mobile, a small circular indicator with a white "m" is shown in the bottom left.
         • Smooth dragging is enabled in windowed mode only.

    All elements are contained within a single ScreenGui.
