FakeUnset

Sentinel marking a positional variable on a FakeBoundStatement that was explicitly left unset (via BoundStatement.unset) as opposed to bound to an actual CQL null (via setBytesUnsafe(idx, null), which FakeBoundStatement records as Kotlin null). Mirrors the real driver's "unset means don't touch this column" write semantics — see StatementBuilder.insertPrimary (uses unset) vs. StatementBuilder.insertPrimaryWithNulls (binds real null, to create a tombstone) for the two call sites this distinction matters for.

Returned in place of a value from FakeBoundStatement.boundValues wherever that index was never bound, or was explicitly unset.
