重大重构：引擎模块拆分 + P0插件实现 + 55个Bug修复

核心变更: - engine.py(1781行)拆分为8个独立模块: lifecycle/security/deps/ datastore/pl_injector/watcher/signature/manager - 新增plugin-bridge: 事件总线 + 服务注册 + RPC通信 - 新增i18n: 国际化/多语言翻译支持 - 新增plugin-storage: 插件键值/文件存储 - 新增ws-api: WebSocket实时通信(pub/sub + 自定义处理器) - nodejs-adapter统一为Plugin ABC模式 Bug修复: - 修复load_all()中store_dir未定义崩溃 - 修复DependencyResolver入度计算(拓扑排序) - 修复PermissionError隐藏内置异常 - 修复CORS中间件头部未附加到响应 - 修复IntegrityChecker跳过__pycache__目录 - 修复版本号不一致(v2.0.0→v1.2.0) - 修复测试文件的Logger导入/路径/私有方法调用 - 修复context.py缺少typing导入 - 修复config.py STORE_DIR默认路径(./mods→./store) 测试覆盖: 14→91个测试, 全部通过

+## 🔧 问题修复
+
+### P0 级修复
+
+| # | 问题 | 文件 | 修复内容 |
+|---|------|------|----------|
+| 1 | 启动崩溃：config.py 语法错误 | `oss/config/config.py:33` | 修复 `"STORE_DIR"` 后缺失的逗号，字符串隐式拼接导致 SyntaxError |
+| 2 | engine.py 超 400 行 | `oss/core/engine.py`（1730 行） | 按组件拆分：lifecycle / security / plugin_manager / data_store 独立模块 |
+| 3 | 语法检查全线通过 | 全部 `.py` 文件 | `py_compile` 零错误，消除所有语法隐患 |
+
+### 遗留问题修复（问题报告.md）
+
+| 严重度 | 原问题 | 当前状态 |
+|--------|--------|----------|
+| 🟢 已修复 | CRITICAL × 4（路径穿越、方法错误、路由空实现、空指针） | 在新架构建模中已复现并修复 |
+| 🟢 已修复 | HIGH × 3（安全检查可绕过、静默吞异常） | AST 解析替代字符串匹配、逐处异常日志 |
+| 🟢 已修复 | MEDIUM × 5（CORS、限流线程安全、CSRF 导入、重复实现、写空数据） | 全部对齐当前架构 |
+| 🟢 已修复 | LOW × 3（空存根、异常静默、配置不一致） | 逐一清理 |
+
+---
+
+## 🛡️ 安全增强
+
+### 新增安全模块
+
+| 模块 | 能力 | 文件 |
+|------|------|------|
+| **JWT 认证中间件** | Bearer Token + JWT 签发/验证，支持 API_KEY 回退 | `oss/core/security/jwt_auth.py` |
+| **CSRF 防护中间件** | Token 校验 + SameSite Cookie，含 `json` 导入修复 | `oss/core/security/csrf.py` |
+| **输入验证中间件** | JSON Schema 校验、参数白名单、类型强制 | `oss/core/security/input_validator.py` |
+| **IP 黑白名单引擎** | 规则持久化、CIDR 匹配、攻击日志记录 | `oss/core/firewall/ip_filter.py` |
+| **HTTPS 支持** | 自签名证书生成、TLS 上下文加载 | `oss/core/security/tls.py` |
+
+### 现有安全增强
+
+- 令牌桶限流器验证修复（线程锁 + `deque` 修正）
+- CORS 预检请求 `Access-Control-Allow-Origin` 对齐配置
+- 插件沙箱 AST 解析替代字符串包含检测
+- `except: pass` 全面审查，替换为最小日志

-# HTML 渲染服务
-
-将存储在 plugin-storage 中的 HTML 页面映射到 8080 端口。
-
-## 功能
-
- 从 plugin-storage 读取 HTML
- 自动注册路由到 web-toolkit
- 支持动态页面访问
- 页面管理（存储/获取/删除/列出）
-
-## 使用
-
-```python
-html_render = plugin_mgr.get("html-render")
-
-# 存储 HTML 页面
-html_render.store_html("index", "<h1>Hello World</h1>")
-html_render.store_html("about", "<h1>About</h1>")
-
-# 获取页面
-html = html_render.get_html("index")
-
-# 列出所有页面
-pages = html_render.list_pages()  # ["index", "about"]
-
-# 删除页面
-html_render.delete_page("about")
-```
-
-## 访问
-
-```
-http://localhost:8080/          → index 页面
-http://localhost:8080/about     → about 页面
-```
-
-## 依赖

-# web-toolkit Web 工具包
-
-提供静态文件服务、模板渲染、路由等 Web 开发工具。
-
-## 功能
-
- **静态文件服务**：提供 HTML/CSS/JS/图片等静态文件
- **模板引擎**：支持变量替换、条件判断、循环
- **路由管理**：为 HTTP 和 TCP 服务器注册路由
- **自动首页**：自动查找 index.html
-
-## 使用
-
-```python
-web = plugin_mgr.get("web-toolkit")
-
-# 设置目录
-web.set_static_dir("./public")
-web.set_template_dir("./templates")
-
-# 添加自定义路由
-web.add_route("GET", "/api/hello", lambda req: {
-    "status": 200,
-    "headers": {"Content-Type": "application/json"},
-    "body": '{"message": "Hello"}'
-})
-
-# 渲染模板
-html = web.render_template("page.html", {"title": "My Page", "items": [1, 2, 3]})
-```
-
-## 模板语法
-
-```html
-<!-- 变量 -->
-<h1>{{ title }}</h1>
-<p>{{ description }}</p>
-
-<!-- 条件 -->
-{% if show_content %}
-  <div>{{ content }}</div>
-{% endif %}
-
-<!-- 循环 -->
-<ul>
-{% for item in items %}
-  <li>{{ item }}</li>
-{% endfor %}
-</ul>
-```
-
-## 配置
-
-```json
-{
-  "config": {
-    "args": {
-      "host": "0.0.0.0",
-      "port": 8080,
-      "static_dir": "./static",
-      "template_dir": "./templates",
-      "index_files": ["index.html", "index.htm"]
-    }
