hermes - 💡(How to fix) Fix [Bug]: DashScope provider defaults to intl endpoint unreachable from mainland China

Problem

The Alibaba Cloud DashScope provider (alibaba / dashscope) defaults to the international endpoint:

# plugins/model-providers/alibaba/__init__.py line 10
base_url="https://dashscope-intl.aliyuncs.com/compatible-mode/v1",

This endpoint is not reachable from mainland China — DNS resolution fails or connections time out. Chinese users who configure DASHSCOPE_API_KEY and try to use DashScope models (qwen-turbo, qwen-plus, qwen-max, etc.) get connection errors with no clear indication that the problem is the endpoint URL.

The correct endpoint for mainland China users is https://dashscope.aliyuncs.com/compatible-mode/v1.

Steps to Reproduce

1. On a machine in mainland China, run hermes setup and configure DashScope with a valid API key
2. Try to chat with any DashScope model
3. Connection fails with timeout / DNS error

Impact

Every Hermes user in mainland China using DashScope hits this. The workaround (setting DASHSCOPE_BASE_URL) exists but is undocumented — users have to discover it themselves through trial and error or reading source code.

Proposed Fix

Option A (minimal): Add a note in hermes setup and provider docs that mainland China users need DASHSCOPE_BASE_URL=https://dashscope.aliyuncs.com/compatible-mode/v1.

Option B (better): Auto-detect. During hermes setup, try the intl endpoint first. If it fails, try the domestic endpoint and suggest it as the default for users in China.

Option C (configurable): Ship a hermes config preset for China users that pre-sets the domestic endpoints for all affected providers (DashScope, and potentially others like Baidu, Zhipu, etc.).

Environment

Mainland China network environment. DNS for dashscope-intl.aliyuncs.com is either unresolvable or returns addresses unreachable from within China.
