   Separate deletion vectors from regular positional delete files during scan 
planning. DVs are identified by having ReferencedDataFile set on a positional 
delete manifest entry (Iceberg v3 spec).
   
   - Add dvEntries bucket to manifestEntries with isDeletionVector() helper
   - In collectManifestEntries: route DV entries separately from pos deletes
   - Add DeletionVectorFiles field to FileScanTask
   - Index DVs by referenced data file path for O(1) matching in PlanFiles
   - Unit tests for classification, matching, and FileScanTask field
   
   Part of #589 (v3 deletion vector support).
