 * Fix missing `taskId` filter and incorrect `IN` clause parameter binding in `JDBCJFRDataQueryDAO` and `JDBCPprofDataQueryDAO`.
 * Remove deprecated `GroupBy.field_name` from BanyanDB `MeasureQuery` request building (Phase 1 of staged removal across repos).
 * Push `taskId` filter down to the storage layer in `IAsyncProfilerTaskLogQueryDAO`, removing in-memory filtering from `AsyncProfilerQueryService`.
+* Fix missing parentheses around OR conditions in `JDBCZipkinQueryDAO.getTraces()`, which caused the table filter to be bypassed for all but the first trace ID. Replaced with a proper `IN` clause.
