YQL-21365: Fix TLangVerProxyNode::Clone

2026-07-03T12:55:10Z

#### Fix TLangVerProxyNode::Clone and add related test cases ✎ - Corrected the `Clone` method implementation to properly handle deep copying of inner nodes using `SafeClone`, ensuring correct node duplication behavior. - Introduced new test cases and canonical data to validate the functionality of `GROUP BY ROLLUP` with `NULLIF` and `COUNT(DISTINCT)` expressions. - Added corresponding test configuration and SQL format validation files to support the new test scenario.

YQL-21068: Fix duplicated preaggregate expr

2026-03-20T15:28:00Z

Here was 2 issues: 1. `Init` return status was ignored and so error suppressed. 2. `PreaggregateExpr` was collected twice. On the first attempt it was replaced with a synthetic column that will be "registered" in a source later, and on a second attempt it was already that synthetic, but not yet registered column and so it's init was failing. commit_hash:4398a075d53d99cbb9b172ebae0a05aff5e2d5a7
