- Update PCB to 8HP format (40x100mm) with v2 component placement - Add automated routing scripts (autoroute.py runs full pipeline headlessly) - Update panel spec and SVG for 8HP dimensions - Board routes in <1 second with 0 unconnected pads Scripts: - autoroute.py: Full CLI pipeline (place → export → route → import → DRC) - autoroute_full.py: Same pipeline for KiCad scripting console - place_8hp.py: Component placement only - route.sh/freeroute.sh: Routing helpers
