🖥️ Cursor IDE 适配: - 新增 /v1/responses 端点（Responses API → Chat Completions 自动转换） - 兼容 Cursor 扁平工具格式 { name, input_schema } - 扩展 /v1/models 模型列表（claude-sonnet-4-5/4/3.5） - 连续同角色消息自动合并（mergeConsecutiveRoles） - content 数组中 tool_use/tool_result 块直接透传 🔧 工具参数自动修复 (tool-fixer.ts): - normalizeToolArguments: file_path → path 字段名映射 - replaceSmartQuotes: 中文/法文智能引号替换 - repairExactMatchToolArguments: 模糊匹配修复 - extractToolResultNatural: 自然语言 tool_result 转换 🚀 流式增量优化: - input_json_delta / tool_calls 按 128 字节分块 - 拒绝重试扩展到工具模式 - 极短响应自动重试 🧪 新增 44 个单元测试 (tool-fixer + openai-compat)
