ROCHESS ENGINE auto play (rage and legit) + game helper

--[[
	rocheese.luau - RoChess! engine panel + autopilot
	Luau, Real executor, client side.

	Uses the game's own modules instead of re-implementing chess:
		ReplicatedStorage.Chess.Engine       board, legal moves, UCI/SAN, FEN
		ReplicatedStorage.Chess.Bot          local search: analyse(fen,moves,sec,depth) / think(fen,moves,persona)
		ReplicatedStorage.Chess.VortexBot    server engine bridge: analyse / think
		ReplicatedStorage.ChessClient.App    live client state: session, board, onBoardMove, playMove

	Squares use Engine.algToIndex64 (bottom-up, a1 = 1, h8 = 64).
	Engine scores are always from WHITE's side of the board.

	Panel: top-right, drag it by the title.
	Arrows on the board:
		green  = best move      blue = second best      yellow = third best

	Presets:
		LEGIT  local engine, plays like a 1500 human (noise + blunders), 5-10s per move
		RAJ    server engine (Vortex), always the best move, plays fast

	Controls: STYLE, DELAY min/max, PLAY BEST/ELO, ENGINE LOCAL/VORTEX, AUTOPLAY,
	          PLAY NOW, COPY FEN, BOT GAME.
	Hotkeys: End auto | Home arrow | PageUp hide | PageDown source | Insert copy fen.
