ORDER BY / GROUP BY Column-Number with COLLATE Ignored

```sql
CREATE TABLE t(x TEXT);
INSERT INTO t VALUES('b'),('A'),('c'),('a');
SELECT x FROM t ORDER BY 1 COLLATE NOCASE;
-- SQLite: A, a, b, c  (case-insensitive sort)
-- Turso:  b, A, c, a  (insertion order)
```

```sql
SELECT x, sum(v) FROM t GROUP BY 1 COLLATE NOCASE;
-- SQLite: a|4, b|2  (a and A grouped)
-- Turso:  a|6       (all grouped as one — GROUP BY constant 1)
```
