"""Fetch set-6 .kicad_pcb sources listed in manifest_set6.json (raw download).

Mirrors fetch_set5.py but reads manifest_set6.json and downloads into
$STRESS_DIR/sources/github_set6/. Set 6 is a 15-board mix of easy/medium/hard
open-hardware boards themed around FPGA/CPLD development boards and
embedded-Linux SBC carrier boards (RISC-V MCU dev boards, Lattice/Xilinx/
CologneChip FPGA boards, Jetson Nano / CM4 / Zynq SoM carriers).
After fetching, run `bash prep_set6.sh` (needs KiCad's bundled python /
pcbnew) to produce boards_set6/ (routed reference) + boards_unrouted_set6/
(stripped input).
