feat: Rust 完整重写 wx-cli（单一二进制，支持 macOS/Linux/Windows）

实现所有核心模块：
- src/crypto/: SQLCipher 4 页解密 + WAL 应用（AES-256-CBC）
- src/scanner/: 三平台内存扫描（macOS Mach VM / Linux /proc/mem / Windows ReadProcessMemory）
- src/daemon/: tokio 异步 daemon，Unix socket IPC，mtime-aware DB 缓存，WAL 监听推送
- src/cli/: clap CLI，自动启动 daemon，完整命令实现
- src/config.rs: 跨平台配置加载，兼容 Python 版 config.json 格式
- src/ipc.rs: 换行符分隔 JSON 协议，与 Python 版兼容
- .github/workflows/release.yml: 四平台自动构建发布

cargo build --release 验证通过，生成 4.8MB macOS arm64 单一二进制
