feat: 适配器 i18n + Provider 动态注册 + SetupView 重构 + jars 资源

- 适配器 i18n 接入（eslint/pmd/sql-lint/stylelint）
- Provider 动态注册机制（registry.ts + providers.json + factory 重构）
- SetupView 全面重构（setupView.ts 新增 600+ 行）
- i18n 消息扩展（messages.ts +210 行）
- 规则导入流程优化（import-service / prompt-builder）
- 新增 PMD jars 依赖及测试用例
