Renaming IMG_1.CR3 alone took the shared IMG_1.xmp along and left
IMG_1.JPG without it. A Stem-named sidecar that a sibling photo file
still uses is now copied (independently, never linked) instead of moved;
the last file renamed takes it. A rollback removes the copy.
Stacked on fix/issue-105-rename-rollback.
