fix(sftp): expose lstat on session-backed copy clients

Ordinary SFTP tasks were marked resumable, which skipped the existing file and directory cp optimizations. Select the non-resumable route only when creating fresh matching-host copies with eligible encodings, keeping transfer-center rows and recursive children consistent. Existing checkpointed transfers retain their saved resumable path; failed cp attempts retain the download/upload fallback.
