fix: ISR dispatch calling convention + PS/2 interrupt enable
Root cause: x86_64-unknown-uefi uses the Microsoft x64 calling
convention where the first argument is passed in rcx, not rdi.
The ISR stub was setting rdi = rsp, but isr_dispatch() read
the frame pointer from rcx, getting garbage → triple fault.
Also:
- Enable PS/2 keyboard IRQ via controller config byte (bit 0).
- Expose read_scancode() and TICKS from interrupt module.
- ps2::poll_key() uses 'sti; hlt' race-free sleep pattern.
