Thank you @CellenLee for taking the time and implementing this, according to https://platform.moonshot.ai/docs/api/chat#public-service-address it seems like moonshot is already OpenAI compatible which means it can be used on Roo Code already.

Unless adding a new provider gives user additional benefits we usually don't add new providers that are OpenAI compatible already.

I'll close the PR but please feel free to let me know if there's additional benefits to having this provider added.

@daniel-lxs hi，We’re Moonshot AI, a startup from China building open, powerful, affordable LLMs for real-world use.
Our latest model, Kimi K2, supports 128K context, strong reasoning, and tool use. It’s currently the #1 open model on LMArena, featured in Nature, and handles 10B+ tokens/day on OpenRouter.

@CellenLee is our colleague. We’re big fans of RooCode, so we submitted this pull request.

We’d like to discuss with you the possibility of having our name, Moonshot, displayed in the same manner as DeepSeek.

we sincerely appreciate your time and consideration.

I couldn't figure out how to reopen this so I merged #6046 instead. Thank you for the contribution!
