965-1000: Don’t force legacy SCP everywhere

Pushing -O unconditionally forces the legacy SCP/rcp protocol and bypasses the SFTP transport that modern OpenSSH uses by default. Many hardened installations deliberately expose only SFTP (for example via ForceCommand internal-sftp), so this change will now fail against those hosts and roll back the security improvements OpenSSH 9.0 introduced.(openssh.com)

Please preserve the existing behaviour and only retry with -O when the default transfer fails with the specific “subsystem request failed” / “sftp-server not found” errors, rather than forcing the downgrade up‑front.

-  command.push("-O"); // use SCP instead of SFTP
+  let forceLegacyScp = false;
+  if (identityPaths?.length === 0 && password) {
+    forceLegacyScp = true;
+  }
+  if (forceLegacyScp) {
+    command.push("-O"); // use SCP instead of SFTP
+  }
