- Replace macOS binary with the 4.7 build where Terrain3D + agent_skinned are native
engine modules (no GDExtension .framework). Fixed C# bindability (set_plugin->Object,
abstract Terrain3DAssetResource, drop dup duplicate bind) so glue generates.
- SHIP GodotSharp alongside the binary (matched pair) — stale/missing GodotSharp causes
"Wrapper class not found for Terrain3D" / ".NET assemblies not found". Engine does not
regenerate it. Un-ignore GodotSharp in .gitignore.
- manifest.json: macOS -> 4.7 (4ba7b5b) + new sha + godotsharp field; drop obsolete
terrain_3d GDExtension section; windows flagged 4.7-pending.
- Add .agents/skills/update-engine (mac+win self-serve install) + README + Forge handoff.
