feat: electrical simulation via ngspice-WASM (eecircuit-engine) Adds full SPICE-accurate electrical simulation to Velxio, behind a lazy- loaded ⚡ toolbar toggle. Arduino / ESP32 / RP2040 sketches now co-simulate with real analog behaviour: correct voltages on wires, real I–V curves on LEDs, working potentiometers, NTC thermistors read by analogRead(), PWM driving RC filters, transistors, op-amps, diodes, MOSFETs, etc. Engine: eecircuit-engine (ngspice compiled to WebAssembly). Main bundle stays at 2.4 MB; the 20 MB SPICE chunk only loads when the user activates electrical mode. Disabled at build time via VITE_ELECTRICAL_SIM=false. Frontend additions: - simulation/spice/: SpiceEngine wrapper + lazy entry, NetlistBuilder with UnionFind over wires, componentToSpice mapping (24 metadataIds incl. real part numbers: 2N2222, 2N3055, BC547, IRF540, 2N7000, 1N4148, 1N4007, 1N4733, LEDs, NTC, op-amp ideal), CircuitScheduler with debounced coalescing, AVRSpiceBridge for quasi-static co-simulation. - store/useElectricalStore: Zustand slice, feature-flag aware. - components/analog-ui/: ⚡ toolbar toggle + SVG voltage overlay. - components/components-instruments/: Voltmeter, Ammeter probes. - 62 tests (spice-*, netlist-builder, component-to-spice, instruments). Sandbox (test/test_circuit/): 47-test validation sandbox that proved the approach (hand-rolled MNA baseline + ngspice pipeline) before porting to the app. Kept as reference. Docs: docs/wiki/circuit-emulation-*.md (13 engineering pages covering architecture, solvers, components, AVR bridge, gotchas, performance, integration plan, API reference, appendix) + electrical-simulation- user-guide.md (end-user facing).
