fix: systematic node wrapping improvements for 12+ additional transformation methods

- Fixed RangeTableSample, XmlSerialize, RuleStmt, SQLValueFunction
- Fixed GroupingFunc, MultiAssignRef, SetToDefault, CurrentOfExpr
- Fixed TableLikeClause, AlterFunctionStmt, AlterObjectSchemaStmt, CreateForeignTableStmt

Improved test pass rate from 158/258 to 178/258 tests (69.0% success rate)
Total improvement: 86 additional tests passing since start (from 92/258 to 178/258)
All methods now use proper node wrapping: const result = { ...node }; return { NodeType: result };
