重构: audit第四批data_change收尾(strategy)

- 新建 audit/data_change.rs(50行 data_change_for_tool/emit_data_changed), audit/mod.rs 451→416(-35)
- pub(crate) re-export emit_data_changed(chat.rs super::super::audit + process_tool_calls裸名路径透明)
- F-09 per_conv保留(本批未触session/conv_id逻辑)
主代grep核验(不cargo避openai-split df-ai中间态): mod data_change/pub(crate)use + data_change.rs fn印证; agent隔离自验cargo 0+test 98
strategy: 单批1-2文件原子; audit/mod.rs余416(process_tool_calls主逻辑+build_write_file_diff/risk/truncate helper); audit四批拆分接近完成
