The pinned SDK (daytona 0.155.0) upload_file() accepts bytes, so the host
NamedTemporaryFile round-trip was redundant and briefly wrote the merged
stdin (which can start with the sudo password line) to the host disk.
delete_file() is delete_file(path, recursive=False); the extra
request_timeout kwarg raised TypeError inside contextlib.suppress, so the
pre-dispatch cancel scrub silently never ran and the staged payload stayed
in the sandbox /tmp.
