Initial commit: multi-platform emulator with PS1 support

Jetpack Compose app with adaptive layouts (phone/tablet/foldable) using
Window Size Classes. Integrates a C++ libretro frontend via JNI for
actual PS1 emulation using pcsx_rearmed, with AAudio output and
ANativeWindow rendering.

- Emulation core architecture with interface for NES, SNES, N64,
  Genesis, PS1, PS2 (PS1 implemented, others placeholder)
- Touch controller overlay with D-pad (diagonal support), face buttons,
  shoulders, and analog sticks
- Bluetooth/USB controller detection and input mapping
- Customizable controller layout editor with drag-to-reposition
- Game library with auto-scan of /sdcard/Games/ subfolders
- Auto-import of libretro core .so from /sdcard/Games/cores/
- Save states and SRAM persistence
