Changed

• Build script restructured: create_sd_image.sh replaces build_and_image.sh
• Firmware binaries (SYSTEM, Image, DTB, ELFs) now live in firmware/ (gitignored)
• MinUI base + extras consolidated into minui/ (gitignored); updating MinUI requires only replacing the contents of minui/
• ROM/Bios directory structure driven entirely from minui/Roms/ and minui/Bios/ — no hardcoded lists in build script
• Removed dev ROM bundling mechanism (no space on EMUELEC partition before first-boot resize)
