rajamesandClaude Opus 5.5 954b4d5f70 feat(kernel): screen=boot keeps the console on the screen until login -- for watching a PC boot

KernelArgs gains screen_boot; cmdline.c parses screen=boot (with or without --; any other value:
off). With it, the v4 boot keeps the console mirrored to the framebuffer after POST, with the TTF
font, and says 'Screen: the console stays on until login (screen=boot)'; login and logout work as
without it, and nothing can be typed without Zuse. Without it, unchanged. For the SER5, which has
no known serial port (ruled 2026-10-28). BRINGUP.md: the smoke test's stick and starforth.cfg.

Tests: screen_boot (new) failed on amd64 and aarch64 before, passes on all three ISAs after;
screen_dark_until_login, screen_dark_after_logout, zuse pass. Acceptance: amd64, aarch64, riscv64 to
[zuse@Hera] ok>, POST 538/538, dict_hash 0xfec8c47cfc6f437f; v4 suite and test-32 0 failures.

Plan: docs/v4.0.0/plans/2026-10-27-stick-4-one-disk.md, Task 5.

src/starkernel/boot/

UEFI boot, kernel-image loading, and boot-time command-line handling.

uefi_loader.c — the UEFI application entry point (BOOTX64.EFI); calls ExitBootServices() to take ownership of hardware, builds BootInfo (memory map, ACPI, framebuffer), and hands off to kernel_main().
elf_loader.c — ELF64 kernel image parsing/loading.
cmdline.c — parses the boot-time kernel command line / starforth.cfg contents (see include/starkernel/cmdline.h, kernel_args.h).
reloc_stub.c, reloc.S — position-independent relocation support for the loaded image.
