BuildSizingFieldStep.setup()

Link coastline and river products, configure the mesh family, and declare outputs.

This method links the coastline convention file and river-network mask file as inputs, calls the mesh-family hook to register any additional family-specific inputs (such as SO-region masks), and declares the output sizing-field file.
