New portio.c module following the virmem.c dispatch-by-address pattern, emulating 8253 PIT channel 2 (speaker frequency), PPI port B (speaker on/off), CGA mode/color select registers, game port (joystick stub), COM1 serial (transmitter-ready stub), and floating bus default (0xFF). OUT/WAIT/MOTOR statements and INP()/STICK()/STRIG() functions now fully functional. Continuous tone generation via PulseAudio pthread worker for programs that drive the speaker through OUT &H43/&H42/&H61.
