GRUB 2.12 port — Ventoy compat layer, EFI kernel, install/update targets
Build system:
- Switch from GRUB 2.04 → 2.12 with Ventoy module via build_grub2_212.sh
- New patch_ventoy_212.py: compat typedefs, mem: protocol, VTOY_CMD_CHECK bypass
- Fix EFI libstub compile with GCC 16 (cflags -std=gnu11 on X86_64)
- Disable busybox CONFIG_TC (broken with modern kernel headers)
- New Makefile targets: install, update, rebuild (single-command USB deploy)
GRUB 2.12 compat fixes:
- Add grub_mem_fs with fs_read/fs_close to kern/file.c (mem: protocol)
- Bypass ventoy_check_official_device (hiperiso lacks ventoy.cpio on ESP)
- Disable VTOY_CMD_CHECK anti-tamper (ESP size != 33554432)
Kernel (hiperiso_defconfig):
- Enable CONFIG_EFI, CONFIG_EFI_STUB, CONFIG_FB_EFI (fixes black screen boot)
- Add CONFIG_FONT_SUPPORT, CONFIG_FONT_8x16
grub.cfg:
- Theme path: try themes/hiperiso/ then themes/ventoy/ (path mismatch fix)
- Kernel cmdline: add console=tty0 console=ttyS0 ignore_loglevel earlyprintk=efi
- Restore ventoy_* function names (matching modsrc binary)
