cp: allow directory merging when destination was just created Previously, when copying to a destination that was created in the same cp call, the operation would fail with "will not overwrite just-created" for both files and directories. This change allows directories to be merged (matching GNU cp behavior) while still preventing file overwrites. The fix checks if both the source and destination are directories before allowing the merge. If either is a file, the original error behavior is preserved to prevent accidental file overwrites. Fixes the case where copying multiple directories to the same destination path would incorrectly error instead of merging their contents. fixes: #9318
