build_grub2_204.sh: Add vlnk/VLNK/Vlnk→hlnk/HLNK/Hlnk sed rules for build-time transformation. Add targeted sed rule to replace VENTOY_GUID hex values (0x77772020,0x2e77,0x6576,...) with HIPERISO_GUID values (0x65706968,0x6972,0x6f73,...) so the binary GUID no longer spells 'www.ventoy.net' in memory. build_gui_all.sh: Fix vlnk.c→hlnk.c reference in GUI build.
