RuntimeBootstrapConfig 枚举的定义存在一个严重问题。当 #[serde(untagged)] 与两个都包装了 RcStr（类似于 String）的变体一起使用时，serde 无法区分它们。在反序列化时，任何字符串值（无论是内联代码还是文件路径）都将被错误地解析为第一个变体，即 Code(RcStr)。这会导致文件路径被当作内联代码处理，从而引发运行时错误。
为了解决这个问题，建议将其中一个变体（例如 Path）修改为结构体，以便 serde 能够根据 JSON 结构进行区分。例如，用户可以通过 { "path": "./bootstrap.js" } 来指定文件路径，通过 "console.log('hello')" 来指定内联代码。
同时，别忘了更新 crates/pack-core/src/client/context.rs 中对应的 match 分支来匹配新的结构 (e.g. RuntimeBootstrapConfig::Path { path } => ...)。
pub enum RuntimeBootstrapConfig {
/// Path to a JavaScript/TypeScript file, as an object: `{ "path": "./bootstrap.js" }`
Path { path: RcStr },
/// Inline JavaScript code, as a string

match 表达式的 Code 和 Path 分支中存在代码重复。创建 bootstrap_source 后的逻辑（即 runtime_entries.push(...)）是完全相同的。建议将这部分通用逻辑提取到 match 表达式之外，以减少重复并提高代码的可读性和可维护性。
let bootstrap_source = match bootstrap_config {
crate::config::RuntimeBootstrapConfig::Code(code) => {
// Inline code: create a virtual source
VirtualSource::new(
project_root.join("__runtime_bootstrap__.js")?,
AssetContent::file(File::from(code.clone()).into()),
)
.to_resolved()
.await?
}
crate::config::RuntimeBootstrapConfig::Path(path) => {
// File path: use FileSource to load the file
let bootstrap_path = project_root.join(path.as_str())?;
FileSource::new(bootstrap_path).to_resolved().await?
}
};
runtime_entries.push(
RuntimeEntry::Source(ResolvedVc::upcast(bootstrap_source)).resolved_cell(),
);

Summary
加个通用的 runtimeEntryBoostrap 配置来往运行时之前插入一些可执行的代码。
目前是为了去适配qiankun的加载。
