*	kernel: implement fork()	user	6 days	1	-0/+2
\| \| \| \| \| \| \| \| \| \|	- sys_fork: switch to a kernel stack, bump-allocate a cart-RAM bank, copy the parent's 8 KiB bank via a WRAM bounce buffer, plant a switch-in frame so the child returns 0 to the post-fork PC, fill the child PCB (shared ROM text) - add AllocRamBank (bump allocator) + FindFreeSlot helpers - demo: init forks; parent prints P, child prints C (PCPC...); nested fork gives three distinct pids (123...) - README: document the fork mechanism, mark syscall status
*	gbos scaffold: working cooperative microkernel (verified ABAB in emulator)	user	6 days	1	-0/+86
	- fix ClearKernelRAM clobbering the kernel stack (only clear $C000-$CBFF) - fix SyscallTrap clobbering DE (buffer arg) during table dispatch - README: run via ~/dev/gbc --headless; note bring-up bugs
