docs(models): add DaoXE multi-protocol gateway custom endpoint example

[seven7763]

why

Document how to use DaoXE with Stagehand through the existing Custom Endpoints pattern (model.baseURL + account API key).

what changed

• Add a DaoXE tab under Custom Endpoints in packages/docs/v3/configuration/models.mdx
• Base URL: https://daoxe.com/v1
• Model form: openai/<your-daoxe-model-id> (exact account-scoped ID from the DaoXE dashboard; no hardcoded public model list)
• Note multi-protocol surface (OpenAI Chat Completions / Responses and Anthropic Messages); Stagehand uses the OpenAI-compatible path
• Note service is not available in mainland China
• Add DAOXE_API_KEY to the troubleshooting env table

DaoXE is a multi-model multi-protocol API gateway. I am a DaoXE maintainer. Examples: https://github.com/seven7763/DaoXE-AI

test plan

• Docs page renders with the new Custom Endpoints → DaoXE tab
• Example matches Stagehand model: { modelName, apiKey, baseURL } pattern used for OpenAI custom endpoints
• Optional: smoke chat against https://daoxe.com/v1 with a real key + account model ID
