新增漏洞复测功能，可从漏洞列表一键创建独立复测对话，继承原始对话历史与模型上下文，支持多轮验证修复结果。复测提示词自动带入已有验证方式，并支持漏洞与会话 ID 占位符替换；验证完成后可更新漏洞状态，追加保存复测证据，便于持续跟踪修复进展。

Added vulnerability retesting with a dedicated conversation branch created directly from the vulnerability list. Each branch inherits the original conversation history and model context, supporting multiple rounds of fix verification. Retest prompts include existing verification guidance and resolve vulnerability and conversation ID placeholders. Findings can then be updated with their verification status and supporting evidence to track remediation progress.
