Replace the hardcoded 0644 defaultFilePerm with a NewFilePerm option on the posix and scoutfs backends, exposed as the --file-perms flag and VGW_FILE_PERMS env var alongside the existing dir-perms option. The mode passed to open() is masked by the process umask, so the O_TMPFILE path now chmods explicitly to match the CreateTemp fallback path and give new objects the configured mode regardless of umask.
