feat(hardware): route the 48V sub-board PCB
Context: the 48V sub-board schematic added R6/R7 (series gate resistors) and D1/D2 (VGS zener clamps) that were not yet on the PCB; the netlist also splits the two gate nets. Approach: scripted pcbnew edit — create the three new nets, reassign gate pads/tracks/vias, cut the two collector-to-gate-bus tracks and place the series resistors inline on them, place the zeners at the shortest reach of the gate/source rails, refill zones. Iterated against DRC: R6/R7 moved to 0402 to satisfy the 0.5 mm board-edge rule inside the screw-keepout corridor. Changes: - R6 inline on the x=162 gate column, R7 inline on the x=126 column (both 0402, schematic footprints synced) - D1/D2 SOD-123 with short stubs to the gate columns and to R2.2/ R5.2 (+BATT rails) - Gate pads, tracks and vias reassigned to Net-(D1-A)/Net-(D2-A); Q11 collector on Net-(Q11-C) - DRC: identical to the 30V baseline (12 keepout + 560 mask-bridge legacy items), 0 unconnected pads; title block rev 0.2-draft - Design note and presentation deck updated (routed PCB render) Impact: the 48V sub-board is now fully designed - schematic and routed layout - ready for bench validation with IRF5210s.
