Walkthrough此次更改主要涉及错误消息的改进、模块图优化以及构造上下文的初始化方式。通过引入并行处理和简化控制流，代码的性能和可读性得到了提升。然而，某些错误处理机制的修改引发了对潜在未处理错误的担忧。这些更新旨在提供更清晰的错误指示和更高效的模块处理。 Changes

移除错误处理可能导致未处理的错误
init方法的返回类型从Result<Self>改为Self，移除了错误处理。这意味着如果方法中的任何操作失败，可能会导致未处理的错误。- pub fn init(config: &ConcatenateConfig, module_graph: &ModuleGraph) -> Result<Self> { + pub fn init(config: &ConcatenateConfig, module_graph: &ModuleGraph) -> Self { let mut all_used_globals = HashSet::new(); config.inners.iter().for_each(|inner| { let module = module_graph.get_module(inner).unwrap(); let ast = &module.as_script().unwrap(); all_used_globals.extend(ConcatenateContext::global_vars( &ast.ast, ast.unresolved_mark, )); }); let mut context = Self { top_level_vars: all_used_globals, ..Default::default() }; context.setup_runtime_interops(config.merged_runtime_flags()); context }建议恢复错误处理机制。

Summary by CodeRabbit
新特性
Script方法中准确描述类型。变更
ConcatenateContext的初始化方法不再返回结果，直接返回上下文实例，简化了返回类型，但可能导致错误管理问题。
