chore(local-inference): bump llama.cpp fork to gemma4-assistant arch support

[lalalune]

The runtime half of the Gemma-4 MTP drafter work. Bumps the llama.cpp fork submodule to the gemma4-assistant arch port (fork PR elizaOS/llama.cpp#32).

With this, the fused engine built from the fork can load mtp/drafter-<tier>.gguf — Google's official Gemma-4 MTP drafter head (gemma4-assistant arch, wired in #9256) — and run separate-drafter MTP.

Validated (Apple M4 Max, Metal)

• The fork loads gemma4-assistant cleanly (no unknown-arch / missing-tensor errors), produces correct output, and gives ~1.1× decode speedup with the real amaranus/Gemma-4-E2B-it-qat-assistant-MTP-Q8_0 drafter via --spec-type draft-mtp.

bcae29e65 (prior gitlink) is a clean ancestor → fast-forward (adds the metal-tbq attn-score fix + the gemma4-assistant arch, +419/−26 across 22 files). Re-point to the squash/merge commit once fork #32 lands.
