Add a laguna-v8 renderer/parser matching the Laguna XS 2.1 template, and fix v2 handling of embedded thinking and structured tool arguments.
Prevent FP16 overflow in Metal's quantized routed-MoE prefill path by scaling the linear branch and folding the inverse into the routing scale. Other backends and token-generation paths are unchanged.
Add comprehensive v2/v8 Jinja parity and parser tests.
* llama: add laguna (poolside) arch via a llama.cpp patch under llama/compat/models
The pinned llama.cpp does not include poolside Laguna yet. Add it as an Ollama-owned source file plus a small registration patch under llama/compat/models/. apply-patch.cmake now applies every *.patch under llama/compat/ (the hooks patch plus each arch patch), so adding an architecture only adds files under llama/compat/models/ and needs no new cmake.
* cleanup patch to keep windows happy
