plan(N.1): scenery via WorldBuilder helpers — implementation plan
Bite-sized TDD plan for Phase N.1. Eight tasks:
1. WbSceneryAdapter (LandBlock → TerrainEntry[] adapter)
2. ACDREAM_USE_WB_SCENERY feature flag scaffold
3. Per-helper conformance tests (Displace / OnRoad / GetNormalZ / RotateObj / ScaleObj)
4. Implement GenerateViaWb alternative path
5. Wire feature-flag dispatch in Generate()
6. Visual verification at landblock 0xA9B1 (manual)
7. Flip flag default-on
8. Delete legacy code paths + mark roadmap shipped
Each task has explicit code blocks, exact dotnet commands, expected
output, and a commit instruction. Conformance tests prove substitution
is behavior-preserving before the dispatch is wired in.
