Initial commit: Busbar Designer

Web tool for designing nickel/copper busbars over cylindrical-cell battery packs (21700, 18650) in hex holders. Flask + build123d backend exports STEP/DXF/SVG; vanilla JS frontend with live preview, multi-project SQLite persistence, snapshot history. Deploy scripts in deploy/ (proxmox-lxc.sh, install.sh, update.sh).
