- Implemented correct macOS-specific MD5 key derivation (Code + Cleaned Wxid). - Improved kvcomm file discovery by including monitordata patterns. - Enhanced wxid normalization for accounts like wxid_xxx_yyyy. - Added robust ffmpeg path detection for macOS (Homebrew/System). - Fixed HEVC bitstream extraction and transcoding flags (-f hevc).

修复了 macOS 4.17 版本微信 DAT 图片解密存在的几个关键问题：
密钥推演修正：修复了 macOS 特有的 MD5(Code + CleanedWxid) 逻辑，解决了解密报错问题。
字节序修复：将 bytesToInt32 修正为小端序 (Little Endian)，解决了 4.17 版本高清图解密后花屏/损坏的问题。
4 字节严苛匹配：将签名校验提升至 4 字节，彻底解决了内存扫描时 1/65536 的误报概率（假阳性）。
WXGF 提取优化：改进了 HEVC NALU 提取逻辑，并增加了对 macOS 系统下 ffmpeg 路径的自动搜索支持。
非常感谢你的程序和思路！
