- 新增 YIELD/SUSPEND_BODY opcode；function* 识别与 yield emit - GeneratorState 全量快照 VM 执行上下文（regs/pc/bytecode/spill/save/try/cell 栈段/迭代器） - 调用时参数初始化（默认值/解构副作用与异常在 g() 时刻生效） - %GeneratorPrototype%/%GeneratorFunction.prototype% 内建对象与 next/return/throw - session GC trace 生成器状态 JsValues；闭包捕获分析补 yield/赋值目标扫描

//! 表达式编译域：表达式分发 + sequence/unsupported。

//!

//! `emit_expression` 按 `Expression` 变体分发到各子模块；本文件还处理

//! 序列表达式（逐项求值取末值）与不支持表达式的报错。
