Extend BYO LLM and add native Alibaba Qwen integration

German Martinez
Port’s BYO LLM support does not currently include Alibaba Qwen models. Adding Qwen would give users more choice among model providers and support teams that use Alibaba Cloud. A native Qwen integration would let the catalog track Qwen usage, licensing, and adoption alongside other providers. Broader provider support also helps users keep pace as model capabilities continue to expand.
