+- crearte-deploy `150927e` (0.5.2): `.gitignore` gains `backups/` so P3 backup-script snapshots (e.g. `backups/prod/20260930T095727Z/`) stop polluting `git status`; the on-disk snapshot is untouched.
+- crearte-deploy `150927e`（0.5.2）：`.gitignore` 新增 `backups/`，P3 备份脚本的本机快照（如 `backups/prod/20260930T095727Z/`）不再污染 `git status`；盘上既有快照原样保留。
