…tsExistByTags - Implement GroupBy LINQ operator with key selectors, aggregates (Count, Sum, Min, Max, Avg), composite keys, and HAVING clauses - Add CheckExistsAsync<T> API with strong-typed ID support and batch query integration - Add EventsExistByTags for checking event existence by tag conditions in DCB scenarios - Add AssignTagWhere operation for retroactively tagging events matching a LINQ WHERE clause - Include tests and documentation for all new features Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
