stevomitric opened a new pull request, #58993: URL: https://github.com/apache/spark/pull/58993
### What changes were proposed in this pull request? Adds end-to-end tests for the nanosecond timestamp types (TIMESTAMP_NTZ(p) / TIMESTAMP_LTZ(p), p in [7, 9]) over the data-manipulation clauses and file formats that had no nanos coverage: - TimestampNanosDmlSuiteBase - INSERT / INSERT OVERWRITE / UPDATE / MERGE (all three WHEN arms) / DELETE against an in-memory row-level V2 table, plus a cross-precision write, all keyed on the sub-microsecond remainder across the NTZ and LTZ families. - TimestampNanosFileRoundTripSuiteBase - Parquet and ORC write→read round-trips asserting the sub-microsecond remainder, precision flooring (p=7/p=8) and NULL all survive, both families. ### Why are the changes needed? These clauses/formats are the highest-risk untested surface for the nanos preview. ### Does this PR introduce _any_ user-facing change? No. Test-only. ### How was this patch tested? New tests. All four subclasses pass (26 tests, ANSI on/off); scalastyle clean. ### Was this patch authored or co-authored using generative AI tooling?
