Summary

Add a heightmap-backed TerrainDesc authoring component with chunked generated meshes.

Why

Large-world editing needs native terrain data that saves as stable authoring state and hydrates into render/collider output.

Implementation notes

Define TerrainDesc with heightmap, chunk size, scale, material layers, and generation settings.
Hydrate chunked meshes and optional colliders.
Keep generated chunks out of saved scenes.
Add terrain actor metadata and inspector basics.

Acceptance criteria

Terrain authoring data serializes and migrates safely.
Hydration produces visible chunked mesh output.
Generated chunks/colliders do not leak into saves.
Terrain can be selected and inspected like other authoring actors.

Tests/docs

Serialization, hydration, and save-strip tests. Update terrain docs and README feature list.
