Sydney RunkleandClaude Sonnet 4.6 82fea763c5 fix: register DeltaValue in SAFE_MSGPACK_TYPES; rename _is_diff_delta; cross-saver benchmark
- Add DeltaValue to SAFE_MSGPACK_TYPES so SQLite and other msgpack-based
  savers don't emit "Deserializing unregistered type" warnings.
- Rename _is_diff_delta → _is_delta_value (leftover from DiffChannel rename).
- Parametrize benchmark by checkpointer: runs InMemory (fast-path) and
  SQLite (get_tuple fallback) in the same table, sharing the _run_turns helper.
