feat: 生成器基础支持(YIELD 帧快照挂起/恢复 + GeneratorPrototype next/return/throw)

- 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
