feat: 方法级代码审查 + 模板导入/预览增强 + SQLFluff 方言 + AI 空响应报错修复

- 方法级审查：CodeLens 触发 + 单次 AI 调用（规则匹配 + 6 维度深度审查），新增 method-extractor / status-cache / codeLensProvider
- 模板导入：severity 保留原始值 + 占位 id、去重对照统一 known-rules、重复提示条双语翻译、箭头展开/折叠 UI、520 条静态规则补 zh/ja 翻译
- SQL：sql-lint 重命名 sqlfluff + sqlfluff.dialect 方言可配置 + 默认方言调整
- ESLint：v9 flat config 接线修复（overrideConfigFile）+ legacy 迁移提示
- AI：空响应 EmptyContentError + 重试一次 + max_tokens 截断专用报错
- JSP：整文件检查走 PMD JSP 规则集 + scriptlet 包装解析 + 行号映射
- 诊断按 severity + 行号排序
