兼容层现在只保留 `current_input_file` 这一种拆分方式；旧的 `history_split` 已废弃，只保留为兼容旧配置的字段，不再参与请求处理。
- `current_input_file` 默认开启；它用于把“完整上下文”合并进隐藏上下文文件。当最新 user turn 的纯文本长度达到 `current_input_file.min_chars`（默认 `0`）时，兼容层会上传一个文件名为 `IGNORE.txt` 的上下文文件，并在文件内容前加入一个明确的 `context note`，提示模型这是被压缩过的历史记录而不是新指令；live prompt 也会显式说明当前处于 compacted-context mode，要求模型用已提供的历史来还原上下文状态并直接回答最新请求，避免把重复工具调用或重复提问当成新的起点。

- 如果 `current_input_file.enabled=false`，请求会直接透传，不上传任何拆分上下文文件。
- 旧的 `history_split.enabled` / `history_split.trigger_after_turns` 会被读取进配置对象以保持兼容，但不会触发拆分上传，也不会影响 `current_input_file` 的默认开启。
