Title: Add auto-dependency plugin for system dependency management

Key features implemented:
- Added new auto-dependency plugin that scans plugin manifests for system dependencies and automatically installs missing ones
- Created SystemDependencyChecker class with support for multiple package managers (apt, yum, dnf, pacman, brew, apk)
- Implemented PL injection interface with functions for scan, check, install, and info operations
- Added context management system in core module for plugin execution environment
- Created example plugin manifest demonstrating system dependency declaration
- Updated .gitignore with comprehensive file exclusion patterns

The plugin provides automatic scanning and installation of system dependencies declared in plugin manifests, integrating seamlessly with the plugin loader through PL injection capabilities.

+# 依赖自动安装插件 (auto-dependency)
+
+## 概述
+
+依赖自动安装插件是一个核心系统插件，用于扫描所有插件的声明文件，检查并自动安装系统依赖。
+
+## 功能特性
+
+1. **扫描插件声明** - 自动扫描所有插件目录下的 `manifest.json` 文件
+2. **系统依赖检测** - 读取每个插件声明的系统依赖 (`system_dependencies` 字段)
+3. **安装状态检查** - 检查这些系统依赖是否已在系统中安装
+4. **自动安装** - 对于未安装的依赖，使用系统包管理器自动安装
+5. **PL 注入接口** - 通过 PL 注入机制向插件加载器注册功能接口
+
+## 使用方法
+
+### 在 manifest.json 中声明系统依赖
+
+其他插件可以在自己的 `manifest.json` 中声明所需的系统依赖：
+
+```json
+{
+  "metadata": {
+    "name": "my-plugin",
+    "version": "1.0.0",
+    "author": "MyName",
+    "description": "我的插件"
+  },
+  "config": {
+    "enabled": true,
+    "args": {}
+  },
+  "dependencies": ["plugin-loader"],
+  "system_dependencies": ["curl", "git", "wget"],
+  "permissions": []
+}
+```
+
+### 通过 PL 注入接口调用
+
+插件加载器加载此插件后，可以通过以下 PL 注入接口进行操作：
+
+| 接口名称 | 说明 | 参数 | 返回值 |
+|---------|------|------|--------|
+| `auto-dependency:scan` | 扫描所有插件的声明文件 | `scan_dir` (可选，默认 "store") | 插件信息列表 |
+| `auto-dependency:check` | 检查系统依赖安装状态 | `scan_dir` (可选，默认 "store") | 检查结果字典 |
+| `auto-dependency:install` | 安装缺失的系统依赖 | `scan_dir` (可选，默认 "store") | 安装结果字典 |
+| `auto-dependency:info` | 获取插件系统信息 | 无 | 系统信息字典 |
+
+### 示例代码
+
+```python
+# 获取插件加载器中的 auto-dependency 功能
+injector = get_pl_injector()  # 从插件加载器获取
+
+# 扫描所有插件的系统依赖声明
+plugins = injector.get_injected_functions("auto-dependency:scan")[0]()
+print(f"找到 {len(plugins)} 个插件")
+
+# 检查依赖安装状态
+result = injector.get_injected_functions("auto-dependency:check")[0]()
+print(f"已安装：{result['installed_count']}, 缺失：{result['missing_count']}")
+
+# 安装缺失的依赖
+install_result = injector.get_injected_functions("auto-dependency:install")[0]()
+print(f"成功安装：{install_result['success_count']}, 失败：{install_result['failed_count']}")
+```
+
+## 支持的包管理器
+
+插件自动检测系统使用的包管理器，支持：
+
+- **Debian/Ubuntu**: apt-get, apt
+- **RHEL/CentOS**: yum, dnf
+- **Arch Linux**: pacman
+- **macOS**: brew
+- **Alpine Linux**: apk
+
+## 配置选项
+
+在 `manifest.json` 的 `config.args` 中可以配置：
+
+```json
+{
+  "config": {
+    "enabled": true,
+    "args": {
+      "scan_dirs": ["store"],
+      "package_manager": "auto",
+      "auto_install": true
+    }
+  }
+}
+```
+
+| 配置项 | 说明 | 默认值 |
+|-------|------|--------|
+| `scan_dirs` | 要扫描的目录列表 | `["store"]` |
+| `package_manager` | 包管理器（auto 为自动检测） | `"auto"` |
+| `auto_install` | 是否自动安装缺失的依赖 | `true` |
+
+## 安全说明
+
+- 插件需要 `*` 权限才能执行系统命令安装包
+- 包安装操作有超时限制（300 秒）
+- 所有安装操作都会记录日志
+
+## 文件结构
