Implements bush and flower spawning on ground tiles based on vegetation density. Adds new assets for bushes and flowers, and introduces multi-mesh rendering for optimized performance. Introduces seasonal color variations for vegetation using a shader for bushes and materials for flowers and grass. Refactors material application into a MaterialManager to handle material assignments over multiple frames. Moves ground tile scripts into a subfolder. Adds floating particles to test scene.
