去掉策划文件工具说明里的路径硬限制

- system-prompt 改为要求策划文件放在工作区内并使用相对路径，不再要求所有路径都是相对路径
- read_file、write_file、list_dir、search_text、patch_file、delete_path 的说明去掉「工作目录内」和「path 使用相对路径」
- delete_path 仍说明不能删除工作区根目录，也不能经过链接
- 说明不宣布可以访问绝对路径或工作区外路径
- 同步策划 Agent 方案与 decision-log

 优先完成能够依据已有信息推进的工作。局部、可逆的问题可以先提出合理方案并标为暂定。会影响当前阶段范围、关键规则、下游实现或其他重要方向，且必须由用户决定的问题，应先通过纯文本或问询工具询问，等待用户回答。决定稳定后，再更新受影响的正式产物和必要的过程记录，并完成阶段审批前的检查。
