feat: add unified entry point and multi-process key extraction
Add main.py as single entry point that auto-detects config, extracts keys, and launches Web UI or decrypts databases in one command. Refactor find_all_keys to scan all Weixin.exe processes instead of only the largest one, enabling multi=account support.feat/daemon-cli

### 1. 配置
|
||||
### 快速开始
|
||||
|
||||
首次运行任意脚本时,程序会自动检测微信数据目录并生成 `config.json`,无需手动配置。
|
||||
确保微信正在运行,以**管理员权限**执行:
|
||||
|
||||
```bash
|
||||
python main.py # 实时消息监听 (Web UI)
|
||||
python main.py decrypt # 解密全部数据库到 decrypted/
|
||||
```
|
||||
|
||||
程序会自动完成:配置检测 → 密钥提取 → 启动。首次运行会自动检测微信数据目录并生成 `config.json`。
|
||||
|
||||
如果自动检测失败(例如微信安装在非默认位置),手动创建 `config.json`:
|
||||
```json

`db_dir` 路径可以在 微信设置 → 文件管理 中找到。
|

|

### 2. 提取密钥
|
||||
### Web UI 说明
|
||||
|
||||
确保微信正在运行,以**管理员权限**运行:
|
||||
|
||||
```bash
|
||||
python find_all_keys.py
|
||||
```
|
||||
|
||||
密钥将保存到 `all_keys.json`。
|
||||
|
||||
### 3. 解密数据库
|
||||
|
||||
```bash
|
||||
python decrypt_db.py
|
||||
```
|
||||
|
||||
解密后的数据库保存在 `decrypted/` 目录,可以直接用 SQLite 工具打开。
