- modifiers-napi: 使用 Bun FFI 调用 macOS CGEventSourceFlagsState 检测修饰键 - image-processor-napi: 集成 sharp 库，macOS 剪贴板图像读取 (osascript) - audio-capture-napi: 基于 SoX/arecord 的跨平台音频录制 - url-handler-napi: 完善函数签名（保持 null fallback） - 修复 image-processor 类型兼容性问题 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
