Fix ISR spin-blocking by reading port $60 directly with inb() instead
of calling mouse_read(), which uses mouse_wait_long (100k iterations)
and would stall the interrupt handler waiting for the next packet byte.
Timer (PIT):
Increase PIT frequency from ~1024 Hz to ~8 kHz (divisor 1193 -> 149)
for more granular timer ticks.
Graphics Refresh:
Replace timer-hook-driven rendering (driver/timers/graphicsrefresh)
with a dedicated 'gfxd' process that runs a continuous render loop,
keeping the vCPU active to avoid NEM/Hyper-V pause-loop descheduling.
Move uidebug from driver/video/ to prog/.
Update FPS calculation to account for 8 kHz tick rate.
USB Hotplug:
Replace timer-hook-driven polling (driver/timers/usbhotplug) with a
dedicated 'usbd' daemon process that sleeps 1s between poll cycles.
Add bounds check in usbcore.usb_check_hotplug for empty HC list.
Cleanup:
Remove old scheduler unit (superseded by processmanager/contextswitcher).
Remove tss unit and tss.init() call from kernel.
Remove unused syslog import from contextswitcher.
Reduce BASE_QUANTUM from 8 to 5.
