refactor: 品牌重命名 + maxTokens 支持 + 设置面板简化

- CodeGuard → Code Purifier / 净码特工（displayName、命令、配置标题）
- 新增 ai.maxTokens 配置项，所有 Provider 及 fixer 传入 maxTokens
- AI 引擎增强：repairJsonEscapes + JSON 解析 fallback + 详细错误信息
- 设置面板规则管理改为文件级（list/delete .yaml），addRule 改为 AI 从 Markdown 生成 YAML
- yaml-parser 简化：移除 config.yaml 的 enable/disable 过滤逻辑
- 审查报告面板：errorBanner 优先显示具体错误、lint 诊断显示 suggestion、移除 translatedDiagnostics 独立渲染
- merger 中 translatedDiagnostics 覆盖原始 lint 诊断 message/suggestion
- HTML linter 配置项、测试用例重写、typescript-eslint 移入 dependencies
