Discover aggregate calls natively inside parenthesized AT operands and supported query-bearing statements, including DML, CREATE VIEW/CTAS, EXPLAIN, and COPY.
Reject unsupported DISTINCT, FILTER, ORDER BY, OVER, and EXPORT_STATE decorations on one-argument AGGREGATE calls, including calls inside AT modifier subqueries. Compatibility lowering could previously produce incorrect totals or NULL results. Preserve DuckDB's multiargument aggregate function and the DuckDB 1.5.5 compatibility frontend.
