feat(serve): upgrade daily driver to qwen3.6-35b-a3b q6_k_xl

Switch `make serve` default to Qwen3.6 UD Q6_K_XL (32 GB, hybrid
DeltaNet, near-lossless) and register it in the model catalog. Add
--jinja to the llama-server launcher so tool/function calling works —
without it clients silently ignore tool definitions advertised by the
server.
