Ensure combined predicates in consecutive `filter()` calls are wrapped in a `PredicateNode`. Previously, the optimizer created a raw `BinaryNode` for merged filters, causing type assertion panics. The expr parser generates `filter(array, predicate)` calls only. This fix ensures that the merged predicate is wrapped as an `ast.PredicateNode`. Adds a regression test.
