- arterials merge onto existing roads and keep distance otherwise
- isolated strata components get a drop-in public connector
- blockless districts fall back to the largest clean rectangle
- sliver districts merge into neighbours (district count is a maximum)
- dressing removes blocking features that cut tiles off the street

Also guarantees one building per district and repairs interiors split
by crossing partitions, both found by the new validation.

Blocks now keep a one-tile margin from water, the map edge and other
districts and get an alley ring; lots are cut as back-to-back rows so
every building has an outdoor-facing wall for its door.

Also makes block fitting recursive so irregular district regions split
into several clean blocks instead of being dropped.
