Initial commit — wiring diagram maker with full feature set

- FastAPI + SQLite backend with routers for diagrams, devices, wires, bundles, connectors, export, and Octopart/Nexar search - Konva.js canvas: ortho/direct/curved routing, wire crossings, harness mode, snap-to-grid, multi-select, drag, resize, undo - Wire features: color/stripe, twisted pair helix, shielded glow, gauge size label, multi-core bundle grouping, length/unit tracking - Device library: connector, terminal block, cable, splice, label, group, relay, fuse, switch, component with custom connector support - Exports: BOM CSV, assembly TXT, JSON, formboard layout, PNG image - Auto-migration for schema changes via ALTER TABLE at startup Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
