Extract distance computation from RotationSlideStrategy into a pluggable
IDistanceComputer interface. CpuDistanceComputer adds leading-face vertex
culling (~50% fewer rays per direction) with early exit on overlap.
GpuDistanceComputer wraps ISlideComputer with Line-to-flat-array conversion.
SlideOffset struct uses direction vectors (DirX/DirY) instead of PushDirection.
SpatialQuery.RayEdgeDistance(dirX,dirY) made public for CPU path.

Add Vector-based overloads to SpatialQuery (ray casting, edge distance,
directional gap, perpendicular overlap) and PartGeometry (directional
line filtering) to support pushing parts along any angle, not just
cardinal directions.
Add Compactor.PushBoundingBox for fast coarse positioning using only
bounding box gaps. ActionClone shift+click now uses a two-phase strategy:
BB push first to skip past irregular geometry snags, then geometry push
to settle against actual contours.
