Subject: [PATCH] test(simulation): rebake golden + atlas fixture for Layer-3
 enrichment (#956)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DrainageBasin gained a territorial_status field, so the Layer-1 golden and the
atlas_response msgpack fixture pick it up. Both changes are additive/
representational — basin/attractor/river selection is unchanged.

- cascade_golden.rs: pass None dominant_faction; golden rebaked (only
  "territorial_status": "FrontierUnclaimed" added per basin).
- gen_fixtures.rs: set the new field in the atlas_response generator; fixture
  regenerated.
