The agent patch implements dialect-aware `TOP`/`ALL|DISTINCT` ordering in both parsing and rendering, adds a dialect capability hook, enables it for Redshift, and includes tests for Redshift `SELECT TOP N DISTINCT ...` round-tripping. This satisfies the task intent despite minor implementation differences from the gold patch (e.g., how `top_before_distinct` is set when `TOP` is absent).
Code Review
The patch is close to the intended change and adds the right dialect hook/tests, but likely does not fully satisfy intent due to incorrect `top_before_distinct` state assignment in parser, which introduces a material correctness/regression risk.
`top_before_distinct` is assigned from `supports_top_before_distinct()` before parsing, so in Redshift it becomes true even for `SELECT DISTINCT ...` without `TOP`. This does not match the field meaning ('whether TOP was located before ALL/DISTINCT') and can cause AST mismatches in equality-based tests/consumers.
