> Investigate Non-ANSI CHAR/VARCHAR type assertions in BasicCharVarcharTestSuite

> Parent: SPARK-60531.
> The Non-ANSI master run on 2026-10-23 fails two BasicCharVarcharTestSuite
> cases with SPARK_ANSI_SQL_MODE=false (JDK 17, Scala 2.13):
> - "SPARK-58794: inventoried shapes do not leak CHAR/VARCHAR under
> standardSemantics": zeroifnull(c) returns a CHAR/VARCHAR type outside the
> test's permitted pass-through list.
> - "SPARK-58794: CHAR/VARCHAR vs non-string follow STRING for compare and
> COALESCE": typeof(coalesce(cast('123' AS CHAR(3)), 123)) returns char(3),
> while the STRING comparison returns string.
> Evidence: https://github.com/apache/spark/actions/runs/39883743642
> Tested commit: fce7d51a3760953097fe34df8aa9a4f5326c74ff
> Related feature work: SPARK-58794.
> Investigate the intended Non-ANSI typing and whether the correction belongs
> in type coercion or test setup/assertions. These are CI observations; local
> reproduction and root cause are not yet established. Verify the focused cases
> with ANSI mode disabled and enabled before proposing a fix.
