+升级核心 Babel 工具链到 Babel 8，并将 Node.js 最低版本提升到 `^22.18.0 || >=24.11.0`。相关包默认采用 ESM 语义，继续同时发布 ESM 与 CommonJS 入口；ESM 产物使用 `.js`，CommonJS 产物使用 `.cjs`，原有公开包名与子路径保持不变。同时收紧 tsdown 的依赖外置策略，避免 ESM 无条件内联可直接消费的依赖，并保证 CommonJS 不会同步加载 ESM-only 依赖。Webpack loader 与 CommonJS runtime 复用同一构建图，避免重复加载 Babel 8 等内联依赖；watch/serve 热更新复用解析缓存并采用轻量 AST 签名遍历，在完整语义约束允许时默认使用 OXC AST 快路径，并在普通 build、不支持的输入或运行时自动回退 Babel，避免冷构建同时加载双解析器。Webpack chunk 直接使用 compilation 产物图独立转译，原生 JS/WXS 才保留输出模块图关联，避免把 runtime bootstrap `require()` 误当作源码链接，降低 MPX、Taro Webpack 等链路的内存和插件处理耗时。Webpack 产物中的 harmony import 注释与 JSDoc import type 不再误触发模块图解析。
