// MAIN world 桥 —— 跑在页面主世界，读取页面 JS 变量（isolated world 读不到）。
|
|
// 协议（对齐竞品 inject.js 模式）：
|
|
// isolated → MAIN: {type:'sc-bridge-req', requestId, keys: [...]} keys 含 '*' 时返回诊断键列表
|
|
// MAIN → isolated: {type:'sc-bridge-res', requestId, payload: {key: value}}
|
|
// MAIN 侧零业务逻辑：只读白名单键、JSON 序列化过滤后回传，不注入任何页面行为。
