Gated on KIMI_TOKEN (CI: E2E_KIMI_TOKEN, a Moonshot platform key), like
the other provider credentials — the matrix skips Kimi when unset. Two
cases cover Moonshot's two wire shapes through the kimi_api catalog
entry: OpenAI Chat Completions against the bare host with kimi-k3, and
the Anthropic Messages API against the /anthropic path prefix with
kimi-k2-thinking, keeping model->provider routing unambiguous while
both records are enabled.
