RP2350A Mini wiretest (KiCad)

End-to-end KiCad molecule pipeline test (publish -> import -> footprint -> wiring) in Hydrogen. Source: Caleb RP2350A Mini (KiCad). Ships the anchored GLB and the .kicad_pcb; the importer feeds the board to the converter to generate machine-pin/contact footprint JSON for 3D-editor wiring. Pipeline validation only.
