…#98) Add DateTruncator static class that builds Expression Trees using DateTime.Year/.Month/.Day CLR properties for cross-DB safe date truncation in GroupBy operations. Supports Year, Quarter, Month, Day hierarchies with integer key encoding and human-readable formatting. Also fix pre-existing AnalysisQueryEngine duplicate constructor conflict (from merged #108 + #109) and remove dead ExecuteGroupBy/BuildGroupKey methods already extracted to InProcessGroupByStrategy.
