Local Ollama exposes cloud models both as "<model>:cloud" and as
"<model>:<size>-cloud" (gpt-oss:120b-cloud). Treat the second form like
the first, requiring a ":" so provider ids such as "gmi-cloud" do not
match. Update the require-side comment and docstrings that still listed
only DeepSeek/Kimi/MiMo or claimed every member 400s without the field.
