test(pty): grant an owned Create pane whose title row is cropped

The targeted batching rerun on Claude Code 2.1.284 left its first report
Write unanswered for 1,372 s and timed out: the viewport began at the
pane's relative file row and rule, with the 'Create file' title cropped
above, so the preview parser rejected the file row as foreign. That row
must now resolve to the owned path and is skipped before the unchanged
line-by-line preview match. Replay controls reject another file, another
directory and an edited preview row.
