fix: keep pushed filter columns in projection pushdown PushDownFilter and PushDownProjection run in the same FixedPoint batch. PushDownFilter moves predicates into `pushdowns.filters` without extending `pushdowns.columns`, and PushDownProjection then overwrites `pushdowns.columns` with the parent plan's required columns. Filter-only columns are pruned out of the scan, so readers receive a predicate that references columns they were told not to read, failing at execution with e.g. `FieldNotFound Column "b" not found in schema` (#6757). Changes: - push_down_filter: when a filter is pushed onto a source that already has a projection pushdown, union the columns referenced by the pushed filters and partition filters into `pushdowns.columns`. - push_down_projection: when pruning a Source, extend the required columns with those referenced by pushed filters so they survive projection pruning. - logical_plan: implement `Source::required_columns` (was todo!()): output columns plus pushed filter columns. - daft-json: drop the reader-side workarounds that re-added predicate columns; the optimizer now guarantees them. Keep clearing the limit when a predicate is present. Invariant: `pushdowns.columns` is None, or it contains every column referenced by `pushdowns.filters` and `pushdowns.partition_filters`. Closes #6757
