kernel: RV1106 6.18.46 patch series + hermetic build wrapper (P1)

Browse Source 
- patches/: the pristine-6.18.46 -> WardenOS delta as a 13-patch, subsystem-split
  series (223 files, ~136K lines: clk, pinctrl, DTs/mach, usb-phy, VOP/panel/rgb,
  mailbox, pvtm, rknpu, rga, aic8800 wifi, audio codec, thermal/rtc/adc/gmac/touch).
  Verified: every patch applies cleanly onto pristine (git apply --check), the full
  series reproduces the hardware-verified tree, and the applied source configures +
  builds the warden dtb + rockchip DRM drivers (rc=0).
- build/build-kernel.sh: fetch+verify pristine (sha256-pinned) -> apply series ->
  warden_defconfig -> zImage + rv1106-warden.dtb. build/warden_defconfig captured.
- CI: `patches-apply` (GitHub-hosted, cached tarball) enforces the series applies;
  `kernel-build` (self-hosted warden-sdk runner, dispatch-gated until registered)
  runs the full build and uploads the image.
