New test cases: - semantics_append_read: basic append/read agreement - semantics_multi_append: multiple sequential appends - semantics_partition_filter: partitioned table with predicate - semantics_delete_read: append then delete - semantics_optimize_invariance: OPTIMIZE metamorphic check - semantics_time_travel: time travel across versions after delete These tables were generated by a hybrid oracle that independently reconstructs table state from the Delta log, verified against delta-rs and DuckDB, and validated against the kernel-rs DAT runner (25/25 pass).
