核心模块 Rust 重构：iNES / UNIF / NSF 解析器、Cart 卡带管理、VS UniSystem、EmuFile 抽象层等纯计算逻辑全部迁移至 Rust，消除手动内存管理风险。
Core modules migrated to Rust: iNES / UNIF / NSF parsers, Cart management, VS UniSystem, and EmuFile abstraction layer moved to Rust, eliminating manual memory-management risks.
C++ 层退化为薄封装：保留硬件初始化、内存映射、GUI 回调等状态相关代码，数据解析与算法逻辑通过 FFI 调用 Rust。
C++ layer reduced to a thin wrapper: retains hardware init, memory mapping, and GUI callbacks; delegates data parsing and algorithm logic to Rust via FFI.
自动 FFI 头文件生成：集成 cbindgen，Rust 导出符号自动生成 C++ 头 fceux11_rust.h，消除手写声明的维护负担。
Automatic FFI header generation: cbindgen auto-generates the C++ header fceux11_rust.h from Rust exports, eliminating hand-written declaration maintenance.
清理旧 fallback：彻底删除 MD5、GUID、调色板、滤波器、通用工具等 11 个 C++ fallback 模块，代码库瘦身。
Irreversible legacy cleanup: permanently removed 11 C++ fallback modules (MD5, GUID, palette, filter, utilities), slimming the codebase.
测试体系建立：新增 ROM 回归测试基线（CTest 4/4）与 Rust 单元测试（137 项），重构不再破坏 ROM 兼容性。
Testing infrastructure established: added ROM regression baseline (CTest 4/4) and Rust unit tests (137 cases), ensuring refactors do not break ROM compatibility.
Workspace 架构升级：拆分为 5 个独立 crate（utils / media / formats / debug / core），版本号统一管理，Qt UI 消除硬编码版本字符串。
Workspace architecture upgraded: split into 5 independent crates (utils, media, formats, debug, core); unified version management and eliminated hard-coded version strings in Qt UI.
