feat(particle): 添加粒子与 Rapier2D 物理碰撞集成 (#295)

* feat(particle): 添加粒子与 Rapier2D 物理碰撞集成

- 新增 Physics2DCollisionModule 模块，支持粒子与场景碰撞体交互
- 支持圆形重叠检测和射线检测两种模式
- 支持 Kill/Bounce/Stop 三种碰撞行为
- 修复 module.update() 参数顺序 bug
- 物理模块自动通过 context 注入，用户只需添加模块即可

* chore: update pnpm-lock.yaml for particle physics dependency

Update lockfile to include @esengine/physics-rapier2d as optional peer dependency.
