The swc preset_env requires the core_js option to be set with the minor version (e.g., '3.37') to correctly include polyfills for newer features. Without this, swc defaults to '3.0' which lacks polyfills for features added in later core-js versions like structuredClone (core-js 3.24+). This fix detects the installed core-js version from package.json and passes it to swc's preset_env configuration.

Fixes #9769
Fix for #9769: 该 Issue 指出 JS Transformer 在处理较新的 core-js 特性（如 3.24 版本引入的 structuredClone）时，未能正确注入所需的 Polyfill，导致旧版浏览器报错。问题根源在于 SWC 默认将 core-js 版本视为 3.0，导致其忽略 3.0 之后添加的特性支持。
