 * Strategy that inserts shipments while preserving the order of existing stops.

 * - append: true → Appends pickup and delivery to end of route (no API call)
 * - afterId/insertAtIndex → Inserts at specified position (no API call)
 * - No position params → Uses Route Matrix API to find optimal insertion points
