Iceberg on-demand lookup source for cache-miss fallback. Iceberg on-demand lookup source for cache-miss fallback.
Implements LookupSource via the native Iceberg scan with a batched
pk IN (...) filter pushed down (with_filter), so all missed keys of a
probe fold into one manifest-pruned scan. KeyAligner handles key decode
and result realignment.
