A user who gives DeepSeek search a key of its own has chosen what that key
pays for, so the route check now applies only to the shared
DEEPSEEK_API_KEY. A literal apiKey, or an apiKeyEnv other than
DEEPSEEK_API_KEY, opens every model route for Messages search and for the
Search and Fetch APIs; a configured endpoint does not, since the search
still sends the shared key. The Web search settings page saves its key
under the section's apiKeyEnv, DEEPSEEK_API_KEY by default, so a key saved
there keeps serving only the DeepSeek routes.
The route refusal now names the settings that give search a key of its
own, and the READMEs, the readiness Agent Note, and the upgrade guide
describe the exception.
