Coalesced BLOB reads use fixed 1 MiB gap and 8 MiB merge-size thresholds. Add
file-io.read-coalesce.max-gapandfile-io.read-coalesce.max-blockcatalog options to tune them. Defaults remain unchanged.The old per-call
max_gapandmax_spanarguments are removed; callers using them must set FileIO options instead.Validation: 131 BLOB and 84 multimodal table tests passed; focused Flake8 and
git diff --checkpassed.
