fix: replace broken /search/v1/user with department traversal + batch_get_id

The old find_user() used /search/v1/user which requires user_access_token,
but the code only has tenant_access_token, causing error 99991663 every time.

New strategy:
1. Email/phone → /contact/v3/users/batch_get_id (fastest, proven working)
2. Name → department traversal + find_by_department (needs contact:department.base:readonly)
3. Both fail → clear error message with suggestions

+### 推荐的微信聊天记录导出工具
+
+以下工具为独立的开源项目，本项目不包含它们的代码，仅在解析器中适配了它们的导出格式。目前微信自动解密测试下来不太稳定，可以先用这些开源工具导出聊天记录，再粘贴或导入到本项目中使用：
+
+| 工具 | 平台 | 说明 |
+|------|------|------|
+| [WeChatMsg](https://github.com/LC044/WeChatMsg) | Windows | 微信聊天记录导出，支持多种格式 |
+| [PyWxDump](https://github.com/xaoyaoo/PyWxDump) | Windows | 微信数据库解密导出 |
+| [留痕](https://github.com/greyovo/留痕) | macOS | 微信聊天记录导出（Mac 用户推荐） |

+### Recommended WeChat Chat Export Tools
+
+These are independent open-source projects — this project does not include their code, but our parsers are compatible with their export formats. WeChat auto-decryption is currently unstable, so we recommend using these open-source tools to export chat history, then paste or import into this project:
+
+| Tool | Platform | Description |
+|------|----------|-------------|
+| [WeChatMsg](https://github.com/LC044/WeChatMsg) | Windows | WeChat chat history export, supports multiple formats |
+| [PyWxDump](https://github.com/xaoyaoo/PyWxDump) | Windows | WeChat database decryption & export |
+| [留痕 (Liuhen)](https://github.com/greyovo/留痕) | macOS | WeChat chat history export (recommended for Mac users) |
+
+> Tool recommendations from [@therealXiaomanChu](https://github.com/therealXiaomanChu). Thanks to all the open-source authors — together for cyber-immortality!
