Fix ttymzdrv compilation, add PCW8256 CPLD project, harden Build_FusionX.sh

- Fix ttymzdrv kernel module build failure with GCC 5.5: - Static variables cannot be initialised from const locals (not compile-time constants in C). Changed to zero-init with runtime sharpmz_init_defaults() - Added -Wno-error to ccflags-y to handle unrecognised -Wno-* flags from the kernel Makefile that GCC 5.5 cc1 rejects under -Werror - Add PCW8256 Quartus project files (.qpf, .qsf, .sdc) - were gitignored by **/build/** rule, force-added to match MZ80A/MZ700/MZ2000 - Make Build_FusionX.sh more resilient: - make image-nocheck failure is now non-fatal (bootanimation needs GLIBC_2.28) - Upgrade image generation errors are non-fatal - Update rebuilt binaries (ttymzdrv.ko, mspi_main) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add --image option to build.sh and fix Build_FusionX.sh paths
