Add ShaderSystem so ECS batch updates can run as GLSL compute kernels: pack float component fields into SSBOs, dispatch, and write back. Script: eve.ShaderSystem extends eve.System with bindFields/update. C++: gpgpu::ShaderSystem + EcsGpu.h View pack/unpack helpers. Co-authored-by: Cursor Agent <cursoragent@cursor.com>
