feat(isometric): tree presets + stable shadow cascades#7824
Merged
Conversation
Five tree shape presets (conifer, tall pine, bushy, oak, round) with layered canopy, dark-to-light gradient, size variation, and offset blobs for deciduous types. Simplified to 2-shape colliders (trunk + canopy envelope) to avoid Rapier contact jitter. Shadow pixel-swimming fixed by snapping the cascade clip_from_world matrix to shadow-texel boundaries in a PostUpdate system that runs after Bevy computes cascades. Single cascade at 4096 resolution keeps shadows stable for day/night without per-frame drift. Camera forward-axis snapping added to further stabilise the shadow frustum alignment.
