GeometrySimplifier/ArcFit now fit arcs that pass exactly through run endpoints while balancing tangency error between trusted and estimated directions, fixing arcs that previously bulged or broke tangent continuity at fillet/compound-curve junctions. GravographIS post processor gains per-layer (engrave/cut) tool passes via a new GravographISPostConfig, so ENGRAVE/ETCH-tagged geometry runs as a separate scribe pass with its own feed/depth and an operator pause before the cut pass (spring-floated spindle needs a tool swap).
