Summary: Extend optimizer-v2 `estimateQueryStats()` with aggregate input-row, input-logical-byte, and output-logical-byte estimates while preserving the existing output-row and column statistics. Input estimates sum scan work after pushdown, include filter-only read columns, scale `TABLESAMPLE SYSTEM`, and become unknown when any scan row count is unknown. `SHOW STATS FOR` continues to consume only the pre-existing fields. Differential Revision: D118522999
Summary: Callers can now estimate logical input and output rows and bytes from SQL or an existing logical plan without physical planning or execution. For example, analyzing `CREATE TABLE t AS SELECT 1` reports one row entering the table write without creating `t`. Parsed statements expose the plan they carry, and wrappers delegate to the wrapped statement. The analysis uses the existing validation path and copies four optional totals from optimizer v2. Filtered table statistics apply only to analysis. Existing execution and `SHOW STATS` behavior is unchanged. Differential Revision: D118555659
