Phase 3: GPU 3D drivers + Phase 1-2 stability fixes — full rollup

ROLLUP of all Phase 1-3 work on branch 0.3.0, targeting a production-ready
console + full graphical desktop under Intel and Virgl/VirtIO-GPU.

=== Phase 1 — Stability ===
 - fbcond: Enter key handler (scancode 0x1C→\n), display map buffering,
   control-char filter in all 7 keymaps, write_event assert
 - build-redbear.sh: auto-rebuild-prefix when fork timestamps are newer
   than prefix/x86_64-unknown-redox/sysroot (was warning-only). Added
   configurable REDBEAR_SKIP_PREFIX_REBUILD guard.
 - build-redbear.sh: set explicit keymap '-K us' in console activation
 - config/redbear-device-services.toml: remove spurious init.d service
   files for redbear-acmd/ecmd/usbaudiod. These USB device daemons are
   spawned dynamically by pcid-spawner, not as boot-time init services.
   Starting them without args panicked the boot flow.
 - relibc: grantpt/unlockpt/ptsname (then deduplicated against stdlib)
 - userutils: cherry-pick upstream getty commit 2834434 (standard C
   ptsname/grantpt/unlockpt)
 - base fork: Russian (ЙЦУКЕН) keymap + inputd control-char filter
   (K_ESC/K_BKSP/K_ENTER → \0, commit 73e44d81 in submodule/base)

=== Phase 2 — Login & Console ===
 - login.rs: restored to 0.2.5-known-good liner-based prompt
 - redbear-upower: removed tokio full/signal features → protection fault fix
 - redbear-power: excluded temporarily (being fixed in other session)
 - tlc version: updated to 0.3.0

=== Phase 3 — GPU/3D Drivers (commit 0898332f7a) ===
Intel i915: FULLY implemented — real ring buffer + MMIO command
submission via GEM DMA → GGTT → i915 render ring, with hardware
head-pointer polling (2M iterations, 50µs backoff). Zero stubs.

VirtIO GPU/Virgl (VirtioTransport): 11 VIRTGPU ioctls (GETPARAM,
GET_CAPS, RESOURCE_CREATE, RESOURCE_INFO, CONTEXT_INIT, EXECBUFFER,
WAIT, TRANSFER_TO_HOST, TRANSFER_FROM_HOST, MAP, CREATE_BLOB) ported
from Linux 7.1 virtgpu_ioctl.c and virtgpu_vq.c.
 - driver.rs: 8 virgl_* trait methods (default Unsupported)
 - scheme.rs: 11 ioctl constants + 8 wire structures + dispatch
 - virtio/transport.rs: PCI capability discovery, feature negotiation,
   control+cursor virtqueue setup, vring descriptor building
 - virtio/mod.rs: real implementations for all 8 virgl_* methods
 - intel/mod.rs: explicit virgl Unsupported stubs

Other changes from active sessions: Cargo.toml version bumps, linux-kpi
headers, libpciaccess recipe, mesa/recipe.toml, kf6 patches, expat,
driver-manager, redbear-sessiond, redbear-compositor, cub, tlc, and
many other local recipes.

graphics(0.2.5): bump Wayland/DRM/Input/expat/seatd to upstream latest stable

Bump the lower-delta graphics-stack lane to real upstream latest stable
on 2026-07-02. Per AGENTS.md fork-adaptation policy, the local patches
in local/patches/{libdrm,libwayland,libevdev,libinput}/ must be re-applied
against the new source trees before the next build; rebase is open work.

Versions resolved against authoritative upstream registries (real latest stable):

  libwayland         1.24.0    -> 1.25.0   (gitlab.freedesktop.org/wayland/wayland)
  wayland-protocols  1.38      -> 1.49     (gitlab.freedesktop.org/wayland/wayland-protocols)
  libdrm             2.4.125   -> 2.4.134  (gitlab.freedesktop.org/mesa/libdrm)
  libxkbcommon       1.7.0     -> 1.9.2    (github.com/xkbcommon/libxkbcommon mirror)
  libevdev           1.13.2    -> 1.13.6   (freedesktop.org/software/libevdev)
  libinput           1.30.2    -> 1.31.3   (gitlab.freedesktop.org/libinput/libinput)
  seatd-redox        0.9.1     -> 0.9.3    (git.sr.ht/~kennylevinsen/seatd)
  expat              2.5.0     -> 2.8.2    (github.com/libexpat/libexpat)

BLAKE3 hashes verified against the actual downloaded upstream tarballs.

Not changed (already at or near upstream latest):
  - dbus 1.16.2 (== upstream latest)
  - xkeyboard-config (no standalone recipe; consumed via libxkbcommon)
  - linux-input-headers (Red Bear original, not upstream)

Patches NOT yet rebased: see local/patches/{libdrm,libwayland,libevdev,
libinput}/. The dependency surfaces they patch (libdrm 2.4.134 has new
DRM modifier code, libwayland 1.25.0 has new server-decoder helpers,
libinput 1.31 has new touchpad gesture tables) will need review before
re-fetch.

Red Bear OS — microkernel OS in Rust, based on Redox

Derivative of Redox OS (https://www.redox-os.org) adding:
- AMD GPU driver (amdgpu) via LinuxKPI compat layer
- ext4 filesystem support (ext4d scheme daemon)
- ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG)
- Custom branding (hostname, os-release, boot identity)

Build system is full upstream Redox with RBOS overlay in local/.
Patches for kernel, base, and relibc are symlinked from local/patches/
and protected from make clean/distclean. Custom recipes live in
local/recipes/ with symlinks into the recipes/ search path.

Build:  make all CONFIG_NAME=redbear-full
Sync:   ./local/scripts/sync-upstream.sh
