   Pushed `c64c08906` with four additional combination tests to lock down the 
interactions DataFusion's runtime row-group pruning path will rely on:
   
   * `test_peek_remaining_row_groups_during_decoding_row_group` — multi-value 
peek mid-`try_decode` iteration (symmetric to the single-value DecodingRowGroup 
test).
   * `test_peek_remaining_row_groups_with_offset_and_limit` — OFFSET + LIMIT 
both push down; verifies the simulated budget chains correctly across Read 
decisions.
   * `test_peek_remaining_row_groups_offset_skips_then_limit_caps` — OFFSET 
silent-skips RG 0, LIMIT then caps RG 1; verifies the Skip path shrinks offset 
rather than treating budget as exhausted.
   * `test_peek_remaining_row_groups_selection_then_budget_skip` — composes 
both silent-skip paths (selection-empty RG + budget-skip RG) in one walk; 
expected empty result.
   
   12 peek tests total (6 original + 6 added), 1232 parquet tests pass, clippy 
clean. Ready for another look whenever you have a moment.
