Register and initialize chained PICs (pic8259), unmask timer and
keyboard IRQs and send EOIs after handling. Add keyboard handler using
pc-keyboard (reads scancode from port 0x60 and logs keys) and a timer
handler, plus IDT entries. Load a kernel data segment (SS) in the GDT.
Make serial/framebuffer writes interrupt-safe, enable the x86-interrupt
ABI, initialize PICs and enable CPU interrupts, and change main to
halt while awaiting interrupts. Bump dependencies and update Cargo.lock
