Struct LinearFilamentVectorPotentialKernel 

pub struct LinearFilamentVectorPotentialKernel<T: Scalar> { /* private fields */ }

Linear filament vector-potential Barnes-Hut kernel.

Tree construction still uses each finite source segment’s full AABB, so the near/far plan is based on the full span of the included filaments. Once a source cluster is accepted as far, the source term is represented as a point current element with a current-element-weighted origin, unit direction, and I*dL magnitude. A magnetic dipole term translated to the same origin is also included so closed or locally cancelling current paths can still contribute to the far vector potential.
