fix(parity): dry-run delete protections, delete-delay actual-removal budget, --info name2

- -n/--delete sends the same protected/size-skipped/scope as a real run, so
  the read-only would-delete walk no longer over-reports (row -> caveat)
- --delete-delay charges --max-delete on actual removals and recursively
  re-scans a refilled deferred directory at commit; independent deferred cap
- --info=name emits the leading ./ root line and name2 'is uptodate' lines
- differential tests promoted from residual pins to rsync parity assertions
