* fix(query): preserve global fetch through physical-optimizer repartitioning Aggregate soft-limit pushdown inserts a global CoalescePartitionsExec(fetch) below an AggregateExec whose input is HashPartitioned/KeyPartitioned. The DataFusion physical optimizer's EnforceDistribution/EnforceSorting passes then dropped or rewrote that fetched coalesce, losing the global limit. Root-caused and fixed in the DataFusion fork (GreptimeTeam/datafusion PR #35); this repo pins to that fix commit and adds regression coverage. - pin datafusion to GreptimeTeam/datafusion 48510c7f5 (fetch preservation fix) - global_limit.rs: adapt to new DF API (input_distribution_requirements, child_distribution, replace_children+Recompute); accept HashPartitioned and KeyPartitioned as partitioning to restore; add regression unit tests - sqlness: extend standalone common ssts and refresh distributed ssts_limit result for the preserved fetch plan Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * refactor: drop dead HashPartitioned compat arms and test wrapper - remove HashPartitioned compatibility matches (pinned DF only emits KeyPartitioned); drop their #[expect(deprecated)] attributes - remove single-use agg_with_limit helper whose seed limit is always overwritten by the soft-limit transform - restore Cargo.lock dependency edges unrelated to the DataFusion pin bump (cargo update --precise had downgraded 26 unrelated packages) Addresses oracle ablation review.
