* fix: 截断器丢失唯一 user 消息导致 API 400

修复 #6196

当对话只有一条 user 消息（长 tool chain 场景：system → user → assistant
→ tool → assistant → tool → ...），三个截断方法都会把这条 user 消息丢掉，
导致智谱、Gemini 等要求 user 消息的 provider 返回 400。

改动：
- 提取 `_split_system_rest()` 去掉三个方法里重复的 system/non-system 拆分
- 新增 `_ensure_user_message()`：截断后如果没有 user 了，从原始消息里补回
  第一条 user，避免违反 API 格式要求
- 删掉 `truncate_by_dropping_oldest_turns` 里把没有 user 就清空全部消息的逻辑
- 5 个新测试覆盖单 user + 长 tool chain 场景，3 个旧测试更新断言

* style: format code
