Mobile john doe R15 animation (fixed)

-[[
	MOVEMENT + DASH SYSTEM (with Mobile support and "John Doe" style intro)
	-----------------------------------------------------------------
	Where to place it: StarterPlayer > StarterPlayerScripts (as a LocalScript)

	- Keeps all the original sprint/dash/animation logic.
	- Automatically detects if the player is on mobile (touch).
	- On mobile, shows an intro in black/yellow with a "scanline"
	  and glitch effect, then reveals two buttons: [R] sprint and [Q] dash.
	- On PC it keeps working normally via keyboard (R and Q).
