vasilito b9874d0941 feat: USB storage read/write proof + full Red Bear OS tree sync

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.

Red Bear OS — Graphical Boot Assessment

Date: 2026-05-03 (updated same day after fixes) Tested: redbear-full harddrive.img in QEMU

Result: Build SUCCEEDED (after fixes)

Original Issue (FIXED)

The make all CONFIG_NAME=redbear-full previously failed due to:

POSIX gap: sem_open/sem_close/sem_unlink were todo!() stubs in relibc, preventing Qt6Core.so from linking. Fixed via P5-named-semaphores.patch (full shm-based implementation).
Config inconsistency: kf6-kwayland and kf6-kidletime depend on libwayland which cannot build. Fixed by marking both as "ignore" (they are orphan dependencies of the already-disabled KWin).
Build system races: Stale stage directories and cargo install overwrite failures. Fixed in src/cook/cook_build.rs and src/cook/script.rs.

Current State

Component	Status
redbear-full build	✅ 0 failed recipes, 4GB image
sem_open/close/unlink	✅ Exported in libc.so (verified: nm -D)
redbear-mini (text-only)	✅ Boots to login on framebuffer
Kernel, drivers, initfs	✅ Works
D-Bus daemon	✅ Starts (verified via serial probes)
redbear-sessiond (login1)	✅ Starts
Evdevd, inputd, ps2d	✅ Registered
Serial debug console	✅ Fixed (uses /scheme/debug/no-preserve with respawn)
KWin / Wayland	🔲 Blocked by QML gate
Greeter UI	🔲 Blocked by QML gate

Remaining Blockers

Blocker	Detail
libwayland	Cannot build: missing `MSG_NOSIGNAL` and `open_memstream` in relibc
kf6-kwayland/kf6-kidletime	Marked "ignore" — temporary, blocked on libwayland
QML gate	kirigami → plasma-framework → plasma-workspace requires QtQuick/QML headers
KWin	Blocked by QML gate
