+ColQwen3 configuration that extends Qwen3VLConfig with embedding projection
+fields. This allows ColQwen3 models to be loaded without trust_remote_code
+by mapping their custom model_type (colqwen3, ops_colqwen3, etc.) to a
+standard config class that vLLM understands.
+
+Supported model_types:
+- colqwen3 (TomoroAI/tomoro-colqwen3-embed-8b)
+- ops_colqwen3 (OpenSearch-AI/Ops-Colqwen3-4B)
+- qwen3_vl_nemotron_embed (nvidia/nemotron-colembed-vl-8b-v2)
