> Calcite planner regressions can be hidden when Frontend retries a query with the Original planner. Add a test-only direct planning harness that exercises Calcite parsing, analysis, logical optimization, and conversion without going through Frontend fallback.
> The harness should expose the optimized logical RelNode immediately before Impala conversion together with client-visible output labels and exact Calcite output types. Add a compact synthetic corpus covering supported operators and an explicitly unsupported complex-type case.
