AJ Isaacs b729f92cd6 fix: correct compactor circle-to-circle directional distance ...

The vertex-to-entity approach in DirectionalDistance only sampled 4
cardinal points per circle, missing the true closest contact when
circles are offset diagonally from the push direction. This caused
the distance to be overestimated, pushing circles too far and
creating overlap that worsened with distance from center.

Add a curve-to-curve pass that computes exact contact distance by
treating the problem as a ray from one center to an expanded circle
(radius = r1 + r2) at the other center. Includes arc angular range
validation for arc-to-arc and arc-to-circle cases.
