feat(panic): FUCK [panic] mode=strict|fallback + realtest image variant

- UTSM panic_full returns in fallback mode (logs [PANIC:FALLBACK] + code + hit count); panic_halt keeps always-halt sites (CPU exception, VMM-E11 LA57, VMM-E15 DSK jump, UTSM-E42 test hook). Call sites given safe continuations. - Mode passed to DSK/FirstInit/login/desktop via DSK_BOOT_FLAG_PANIC_FALLBACK; DKM kernel_api.panic / kern.log.panic return to driver; ext4 fatal aborts the op via setjmp/longjmp and DSK falls back to FAT32 ESP. - build.ps1/Makefile: dev=strict, release=fallback, new realtest (release options + strict); default -Variant all; serialized iso packing under -j. - Fix '*/' inside comments (dkm.h, kernel_api.h, bus.c) that broke the build. - Includes pending work: dkm_bus service bus, mt7920/wlan drivers, desktop files/startmenu/prank, pe-tools, diskinfo, docs.
