FCEUX11 v0.2.8

• MD5 哈希计算改用 RustCrypto md-5 crate，消除手写算法维护负担，支持 SIMD 优化。
• Replaced handwritten MD5 with the RustCrypto md-5 crate, eliminating maintenance burden and enabling SIMD optimizations.
• GUID 生成改用标准 UUID v4（uuid crate），消除低质量 rand() 随机性，解析更健壮。
• Replaced low-quality rand()-based GUID generation with standard UUID v4 (uuid crate), providing more robust parsing.
• 通用工具函数 uppow2 改用 Rust 标准库实现，作为端到端流水线验证样板。
• Replaced uppow2 with Rust std implementation, serving as the end-to-end pipeline validation template.
• WAV 音频导出改用 Rust 安全文件 I/O，消除手动 fputc 字节序操作，文件句柄由静态 Mutex 管理。
• Migrated WAV audio export to Rust safe file I/O, eliminating manual fputc byte-order operations with file handles managed by a static Mutex.
• OS 工具函数（mkdir / mkpath / file_exists / msleep）改用 Rust 标准库，解耦 Win32 API 硬编码，为未来跨平台构建打基础。
• Migrated OS utilities to Rust std, decoupling hardcoded Win32 APIs and laying groundwork for future cross-platform builds.
• Unicode 转换（UTF-8/16/32）改用 Rust 安全实现，slice 边界检查替代 2001 年风格的手动指针算术，消除缓冲区溢出风险。
• Migrated Unicode conversions to safe Rust, replacing 2001-style manual pointer arithmetic with slice bounds checking to eliminate buffer overflow risks.
• 时间戳计时改用 std::time::Instant 跨平台纳秒计时器，消除 Windows QPC/TSC 手动校准代码，保留 C++ timeStampRecord 类外壳，调用方零侵入。
• Replaced timestamp timing with std::time::Instant cross-platform nanosecond timer, eliminating manual Windows QPC/TSC calibration while preserving the C++ timeStampRecord class shell with zero caller intrusion.
• 所有模块遵循统一的 Wrapper-Shim + Feature-Gate 范式：#ifdef FCEUX11_RUST_ENABLED 时调用 Rust FFI，否则自动回退到原 C++ 实现。
• All modules follow the unified Wrapper-Shim + Feature-Gate pattern: delegate to Rust FFI when FCEUX11_RUST_ENABLED is defined, otherwise automatically fall back to the original C++ implementation.
• Rust cargo test 42 项全部通过；CMake MSVC Release 构建通过；FCEUX11_RUST_ENABLED=ON/OFF 双配置均编译链接成功。
• Rust cargo test: 42/42 passed; CMake MSVC Release build passed; both FCEUX11_RUST_ENABLED=ON and OFF configurations compile and link successfully.
