## Summary Part 1/15 of ORC predicate pushdown implementation. Adds foundation for statistics-based predicate pushdown: - Add `GetStripeStatistics()` API to ORCFileReader - Forward declarations for liborc types - Infrastructure for accessing ORC stripe-level statistics This is the first building block that enables stripe filtering based on column statistics. ## Changes - `adapter.h`: Add GetStripeStatistics API - `adapter.cc`: Implement statistics retrieval ## Rationale ORC files store min/max statistics at the stripe level. This API exposes those statistics to enable predicate pushdown at the Dataset API layer, following the same pattern as Parquet row group statistics.
