Description
Problem: no delete, vacuum, or partition removal exists; the only row removal is a predicated overwrite that happens to exclude rows. No way to drop a DataItem, retire a feature set/column, or delete a hierarchy.
Fix: explicit remove operations complementary to #13, plus a vacuum/tombstone policy. Test-first development (use the conventions from #28).

Research direction
Read issue #13 for the existing output operations and issue #28 for the test conventions before locating their implementation and tests. Define the DataItem, feature-set/column, hierarchy, partition, delete, and vacuum behaviors, then add tests covering explicit removal and the tombstone policy.
