- Implement flicker-free atomic double-buffered frame rendering and sub-tick input polling in userland/lazybox/snake.c - Add multi-input support (PS/2 keyboard scancodes and serial ANSI arrow escape sequences) - Add sound effects (food beep, game over chime) and live speed scaling (+/- keys, P to pause) - Add POSIX /dev/shm shared memory subsystem in ipc/shm_posix.c and include/ipc/shm_posix.h - Add DNS resolver cache with TTL tracking in net/ipv4/dns_cache.c and include/net/dns_cache.h - Add audio tone and jingle synthesizer in sound/beep.c and include/sound/beep.h - Add %o octal formatting support in lib/vsprintf.c - Add LazyBox applets: 'shm', 'dnscache', and 'beep'
