The lazy buffer path was issuing separate request_ranges() calls per buffer within a segment, bypassing SharedSegmentSource deduplication and SegmentCache. This caused N I/O requests per segment instead of 1, with catastrophic impact on S3 (2x slower on some queries). Key changes: - materialize_selection: Selection::Range now uses request() + local slice instead of request_ranges(), benefiting from caching and deduplication when multiple buffers share the same segment - Replace resolve_filter() with effective_selection() returning Cow<Selection>, avoiding a full LazyBufferHandle clone on every slice()/select_ranges() call when no filter is pending - Add MAX_SPARSE_RANGES (32) limit in materialize() to prevent hundreds of tiny I/O requests from scattered masks - Downgrade hot-path tracing from debug! to trace!
