Preserved terrain across updates

- Saved chunks retain their natural geometry and generation ownership
- Future chunks blend against frozen terrain boundaries
- Build revisions capture generation source and dependencies automatically
- Native terrain queries use contained transition geometry and final height caches
- Historical searches retain recorded pack identities and placement facts
- World creation and Studio updates preserve native lifecycle ordering
- Hydrology containment and scoped content workers retain generation context
- Pregeneration validates saved completion before trusting cached progress
