/cwd 原来直接把参数写入 session、不做任何校验，输错路径后下次对话 claude 会在不存在的 cwd 里 spawn 失败，错误很隐晦、难排查。 - 展开 ~、把相对路径解析为绝对路径（基于当前工作目录） - 校验目标存在且确实是目录，否则提示并拒绝切换 - 存储解析后的绝对路径，与 /send 的校验风格保持一致
手机输入法或 markdown 代码格式常给路径自动加上反引号或引号（如 \`/path\`、'/path'），导致路径开头不是 / 被当成相对路径拼接、校验失败。 切换前先剥离首尾的反引号/单双引号/空格。

/cwd原来直接把用户输入写入 session，不做任何校验。一旦路径输错，下次对话时claude会在一个不存在的cwd里 spawn，导致失败，且错误信息隐晦、难以排查。（对比之下/send已经有existsSync校验，/cwd缺。）改动
~、把相对路径解析为绝对路径（基于当前工作目录）/send的校验风格保持一致验证
npm run build（tsc）通过handleCwd四种情况：存在目录→切换、不存在→拒绝、是文件→拒绝、空参→显示当前 —— 全部符合预期
