全量 Rust 重写 Fig 编译器前端。 Lexer: 43 个测试，千行压力测试通过，完整 UTF-8 支持（中文标识符/字符串），运算符最长匹配打表，单行/多行注释 + 错误恢复。 Error System: Diagnostic trait + Warning/Error/Critical 三级严重度，源码上下文渲染（Unicode 波浪线、中英双语 i18n），SourcePosition/SourceRange 为 LSP 准备，Related 关联信息，thrower 宏追踪编译器源码位置。 Build: cargo + build.rs（git hash + 编译时间戳）。 删除全部 C++ 源码。
