Claude Code v2.1.237 发布：修复 LLM 网关提示词缓存，新增“简洁”输出风格

What’s changed

• Fixed prompt caching for sessions using an LLM gateway or custom base URL
• Added a built-in “Concise” output style: Claude leads with results and skips preamble and narration, while doing the work just as thoroughly. Select it under Output style in /config.
