Harald Hoyer 0c262db0eb feat(overlay): track unstable llama-cpp (b9608) for Gemma4 MTP 
The CUDA build (amd) used the stable-channel llama-cpp (b9190), which
predates the Gemma4 MTP draft architecture ('gemma4-assistant',
llama.cpp PR #23398, first shipped in b9549). As a result gemma-4-31b's
--spec-type draft-mtp aborted at load with "unknown model architecture:
'gemma4-assistant'".

Inherit llama-cpp from the unstable channel (b9608) so the CUDA build
gets the new draft arch, and drop the explicit b9264 src pin on
llama-cpp-rocm so the ROCm build (halo) tracks the same base. Both now
resolve to b9608; bf16 KV cache avoids the Q8-KV 0%-acceptance issue
noted in the PR.

Using the Configurations

Install a system via nixos-anywhere

$ nix run github:numtide/nixos-anywhere -- \
  --flake 'git+https://git.hoyer.xyz/harald/nixcfg'.#hostname \
  root@hostname --no-reboot --tty -i $HOME/.ssh/id_ed25519
... enter disk password
$ ssh -t root@hostname systemd-cryptenroll /dev/luksdev --wipe-slot=tpm2 --tpm2-device=auto --tpm2-pcrs=1,15

Update NixOS system

$ nixos-rebuild --use-remote-sudo -L --show-trace --refresh --flake git+https://git.hoyer.xyz/harald/nixcfg boot

Update macOS system

$ darwin-rebuild -L --show-trace --refresh --flake git+https://git.hoyer.xyz/harald/nixcfg switch

Update home-manager configuration

$ nix --refresh run 'git+https://git.hoyer.xyz/harald/nixcfg' -- \
  switch -b backup --flake 'git+https://git.hoyer.xyz/harald/nixcfg'
