Adds USB host-mode game controller support, focused on the NES Joy-Con via the 8BitDo USB Wireless Adapter 2 in PS-Classic mode, the only adapter mode the Samsung Fold 6 kernel will bind as a real gamepad. Includes a Test Controller screen under Settings with live button/axis indicators, a USB device enumeration view, and a scrolling raw event log for debugging. Also ships a batch of stability fixes discovered during controller bring-up: white-screen-on-USB-detach (missing configChanges for keyboard/navigation tore down MainActivity when the gamepad disappeared), OOM during in-game input delivery (cover-art bitmaps decoding at full resolution), and a FLAG_KEEP_SCREEN_ON on GameScreen to keep the system out of the deeper sleep states that aggravate OTG selective-suspend. Captures a design direction for replacing the 8BitDo adapter entirely with a DIY ESP32-WROOM-32 Joy-Con bridge that re-advertises as a BLE HID gamepad. Not implemented yet — docs only.
