PartitionsTable.withFilter() was a no-op (TODO), causing full manifest scans when querying with partition filters. This adds predicate pushdown following the same pattern as BucketsTable (apache#7592) and FilesTable (apache#7376). Key changes: - PartitionsScan extracts partition predicate via LeafPredicateExtractor - PartitionsSplit carries the predicate to PartitionsRead - Catalog path: in-memory filter preserving metadata columns - TableScan path: manifest-level pushdown via withPartitionFilter - PartitionPredicateHelper refactored to build+apply two-step pattern - parsePartitionSpec extended for key=value/key=value format Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
