RecomputeNormals()

void RecomputeNormals	(	Span< FVertex >	verts,
		Span< const uint32_t >	indices
	)

Recomputes smooth per-vertex normals from positions over an indexed triangle list.

Area-weighted face-normal accumulation, then normalize. Needed after POSITION-only morph deformation (which moves vertices without supplying normals); run it on the morphed vertices before packing/skinning so shading matches the deformed surface. Tangents are left as-is (re-projected onto the new normal frame by FQVertex::PackTBN).
