Feature: 在版本获取失败的情况下提供移除依赖的选项


Review the attached screenshot and locate the WebUI flow for dependency version retrieval. The issue names no file, test, or entry point, so first determine where that failure is handled and clarify the expected removal behavior. Done means the requested removal option is available when version retrieval fails and its behavior is covered by the relevant checks.
