26-29: 构造函数EnvReplacer::new的改动看起来不错。使用
HashMap<String, Expr>简化了数据结构，可能提高了性能。
33-34: 函数get_define_env的实现是正确的。使用
cloned()方法来返回一个拥有的值是高效且清晰的。
139-143: 函数build_env_map的实现是正确的。该函数正确地将 JSON 值转换为表达式，逻辑合理且使用了适当的辅助函数。
318-415: 测试用例的实现是全面的。新增或修改的测试用例涵盖了多种场景，确保了环境变量处理逻辑的正确性。对于不支持的情况，使用
should_panic测试是合适的。

HashMap<String, Expr>简化了结构体定义，提升了代码的可维护性和性能。
26-29: 更新new方法以简化初始化。使用
HashMap<String, Expr>初始化EnvReplacer，与结构体的简化设计保持一致。
33-34: 简化环境变量检索。
get_define_env方法直接从defineHashMap 中获取值，简化了环境变量的检索过程。
39-108: 改进环境变量解析逻辑。
visit_mut_expr方法通过构建成员访问路径来处理嵌套属性，提升了环境变量解析的灵活性和代码的清晰度。
120-124: 更新build_env_map的返回类型。返回类型更新为
Result<HashMap<String, Expr>>，提高了错误处理和类型安全性。
299-374: 新增测试用例验证功能。添加了针对深层点键和计算属性的测试用例，确保新实现的正确性并覆盖边界情况。
