Introduce a WorldGen module under Simulation with reusable helpers for
seed-based terrain heightmaps: PerlinNoise (deterministic 2D gradient
noise), FractalNoise (fBm over octaves), Falloff (island edge masks),
Heightmap (row-major grid with min-max normalize) and HeightmapGenerator
(settings to normalized heightmap). All deterministic from an integer
seed, allocation-free per sample, covered by xUnit tests.

Updated the organization of engine libraries to group features by architectural role rather than by individual feature. Enhanced documentation in CLAUDE.md and architecture.md to reflect these changes. Removed obsolete project references and added new modules for content management and simulation. Adjusted project files for MrGameEng.Graphics and MrGameEng.UI.Tests to align with the new structure.
This refactor aims to streamline the development process and improve clarity in the engine's architecture.
