[YouNeedCryDear]

What this PR does

Adds OME configuration for serving Qwen 3.6 35B A3B with a 1M context window:

• Adds the qwen3-6-35b-a3b ClusterBaseModel pointing to hf://Qwen/Qwen3.6-35B-A3B.
• Adds the vllm-qwen-3-6-35b-a3b ClusterServingRuntime with vLLM settings for Qwen3_5Moe, 2-way tensor parallelism, long-context rope overrides, multimodal limits, Qwen reasoning parsing, and tool-call parsing.
• Registers the runtime in config/runtimes/kustomization.yaml.
• Adds a sample InferenceService for the Qwen namespace.

Why we need it

This enables OME to select and deploy a dedicated runtime for Qwen 3.6 35B A3B, including the long-context configuration required for 1M-token serving.
