-PLUS API domains are selected from `env.PLUS_API_KEY` after trimming surrounding whitespace. With `sk-` followed by 24 characters, all services use `https://deepcode.vegamo.cn`. With 26 characters, LLM requests under `/plugin/openai/**` (including `/models` subscription probes and connection warmup) use `https://api.deepcodeplus.com`; all other services use `https://www.deepcodeplus.com`, including web search, image understanding, image/video generation, telemetry, and cost estimates. Without a key, anonymous plugin requests retain the legacy host. No additional suffix character restriction applies. An explicitly configured invalid value (including an empty string or non-string) produces an error even when `subscriptionPlan=off`. In the URLs below, `{llmHost}` refers to the selected LLM domain.

 `subscriptionPlan` accepts `default`, `on`, or `off`; missing or invalid values use `default`. The regular connection retains the user/project/environment precedence described above.
