/**
 * 百炼 (Alibaba DashScope Bailian) Coding Plan wrapper. Exposes
 * third-party models — including GLM-5 and Kimi K2.5 — through a
 * single DashScope endpoint, so the same API key (`DASHSCOPE_BAILIAN_CODING_KEY`)
 * covers multiple target models. Cribbed from builtin-provider-presets.ts
 * `bailian-coding` preset.
 *
 * Default baseURL: https://coding.dashscope.aliyuncs.com/v1 (CN).
 * Override via `BAILIAN_BASE_URL` if you need the -intl variant.
