-- Adds RouteStop.travelMinutesToStop: admin-configured travel time (minutes) from the
-- previous stop, used to compute each stop's estimated arrival time (replacing/augmenting
-- distance-proportional interpolation). Nullable — falls back to distance interpolation
-- when unset.
-- Uses IF NOT EXISTS following the pattern established in
-- 20260719000002_repair_route_checkin_minutes, after this same table had two migrations
-- checked in as empty "applied directly" placeholders that never reached the deployed DB.
