* test: cover windowed sort cast unit mismatch Signed-off-by: discord9 <55937128+discord9@users.noreply.github.com> * fix(query): stop windowed sort on unit- or timezone-changing time casts A cast on the time index column keeps the windowed-sort optimization eligible only when it preserves the underlying timestamp values. Casts that change the time unit (e.g. ms -> s) or that add a timezone to a naive timestamp re-interpret the values, so the working ranges derived from the time index no longer describe the sort column and the scan fails with a working-range error or silently wrong order. Reject both cast shapes so such queries fall back to the normal SortExec path. The integration fixture uses two rows 1000 seconds apart so the cast output stays distinct and the ordering assertions are not vacuous; the descending arm gets its own expectation.

The wrapper branch now applies the same unit- and value-preserving predicate as the cast branch, with the predicate extracted into preserves_timestamp_values and shared by both. The integration regression gains to_timestamp_seconds ASC/DESC arms and a to_timestamp_millis value-preserving control; unit tests cover unit-changing, tz-adding, and non-timestamp wrapper inputs.

Both wrappers change the time unit inside the function, so the windowed-sort rule no longer applies and the plans render a plain SortExec. Query results are unchanged; only the EXPLAIN plan line differs. Regenerated by the sqlness runner.
