New delete behavior option: "Archive deleted" — when a file is deleted from the phone in a TWO_WAY pair, it moves to _Deleted/<path> on remote instead of being permanently deleted from the backup. Also allows storage root (/storage/emulated/0) for UPLOAD_ONLY pairs so whole-phone backup syncs work; only blocks root when sync direction would write files locally.
