Module equality_delete 

Equality delete filter — Phase H.

Loads Iceberg equality delete files from the object store and builds an in-memory predicate set. Applied to each RecordBatch during scan to mask logically deleted rows.

Scope: single-column equality predicates (most common pattern: document_id, agent_id, session_id). Multi-column AND predicates are supported as long as each column is checked independently (conservative: a row is deleted if ALL delete-file columns match).
