v2.13.0

Three new providers — Kimi (Moonshot), Grok (xAI), and Qwen (Alibaba) — covering the major coding models. Kimi and Qwen include their flat-fee coding-plan subscriptions alongside pay-per-use; Grok adds graded /thinking effort.

Added

• Kimi (Moonshot AI). kimi drives the Kimi Code subscription
  (api.kimi.com/coding, model alias kimi-for-coding); kimi-api is
  pay-per-use (api.moonshot.ai, default kimi-k2.7-code); kimi-cn for
  mainland China. Keys: KIMI_CODE_API_KEY / MOONSHOT_API_KEY.
• Qwen (Alibaba Model Studio). qwen drives the Coding Plan
  subscription (coding-intl.dashscope…, sk-sp- key); qwen-api is
  pay-per-use (DashScope, default qwen3-coder-plus); plus qwen-cn /
  qwen-cn-api and a free ModelScope tier (modelscope). Keys:
  BAILIAN_CODING_PLAN_API_KEY / DASHSCOPE_API_KEY / MODELSCOPE_API_KEY.
• Grok (xAI). grok — pay-per-use (api.x.ai), default grok-build-0.1
  plus grok-4.3 and the fast/reasoning variants. Key: XAI_API_KEY.

Changed

• /thinking now covers Grok (reasoning_effort — low/medium/high). Kimi
  and the Qwen coder models have no graded knob, so they stay out of the picker.
• Qwen tool turns are sent non-streamed. DashScope rejects tools with
  stream:true, so agent turns that carry tools buffer the reply (handled
  transparently); other providers keep streaming.
• Kimi K2.x code models fix temperature internally — Codeep withholds the
  sampling params so they don't 400.
