Review Comment:
Added planner-path regression coverage in
372436222407013a13e6312bfd574abb283af763. The new information_schema_p0 suite
checks UPDATE_TIME-only, TABLE_NAME+UPDATE_TIME, TABLE_NAME-filtered
projection, and a full-status contrast case so the schema scan tuple pruning
path is covered beyond the hand-built FE RPC requiredColumns tests.
