Closes #198 Picks up where #209 left off with @Fokko's feedback addressed. Thanks @jayceslesar for the original work. # Rationale for this change Adds `CAST(column AS type)` parsing that maps to Iceberg transforms (`date` → `DayTransform`, `year` → `YearTransform`, `month` → `MonthTransform`, `hour` → `HourTransform`). Also implements `BoundTransform.ref()` and `eval()` — both were missing abstract methods required by `BoundTerm`. Introduces `UnboundTransform` with `bind()` that validates via `can_transform()`. ## Are these changes tested? Yes. 11 new tests covering all transform types, case insensitivity, nested fields, unsupported types, comparison operators, and boolean composition. ## Are there any user-facing changes? No. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
