Add redbear-usb-storage-check in-guest binary that validates USB mass storage read and write I/O: discovers /scheme/disk/ devices, writes a test pattern to sector 2048, reads it back, verifies match, restores original content. Updates test-usb-storage-qemu.sh with write-proof verification step. Includes all accumulated Red Bear OS work: kernel patches, relibc patches, driver infrastructure, DRM/GPU, KDE recipes, firmware, validation tooling, build system hardening, and documentation.
