DeepSeek's official API has a single endpoint, https://api.deepseek.com,
with servers physically in China. There is no separate mainland endpoint,
and api.deepseeki.com is a typo grandfathered into the source.
The /zh/install "国内 API 访问" panel previously suggested users set a
custom base_url to a China endpoint, which doesn't exist. Replace with
the truth: the default works for mainland users; only override
DEEPSEEK_BASE_URL if you have a private mirror.
Also re-runs derive-facts to keep facts.generated.ts at 9 providers.
