David Montero f5c1887869 fix(sim): model slide-switch as a real SPDT + tie ESP32 dual 3V3/5V pins to the rail
The slide-switch SPICE model only wired pin 1 <-> pin 2 (an SPST), ignoring
pin 3. The part is really an SPDT whose common wiper (pin 2) selects pin 1 at
value=0 or pin 3 at value=1, so a switch wired GND-1 / signal-2 / VCC-3 (the
natural Wokwi hookup) could never pull its signal high. Fixes the reported
ESP32-C3 case (issue #247) where only the green LED lit and the switch never
toggled the red one.

Second cause on that board: the ESP32-C3-DevKitM-1 exposes its supply as
3V3.1/3V3.2 and 5V.1/5V.2 (there is no bare 3V3/5V pin). VCC_PIN_RE has no
numeric-suffix branch on purpose (a dual-supply pin such as L293D VCC2 must
not collapse onto the shared logic rail), so those numbered pins floated at
0 V and the switch's HIGH side was dead. List them in boardPinGroups for
esp32-c3 / esp32-s3 / esp32-cam.

- componentToSpice: SPDT emission (both throws, complementary 0.01/1e9 R).
- digitalGateEngine: both driveSwitch paths (all-digital + mixed) made SPDT to
  match, so the pure-digital paint and the ngspice solve agree.
- examples-digital / examples-circuits: rewire every slide-switch so the rail
  feeds pin 3 and pin 1 is the value=0 throw, preserving value=ON=HIGH.
- spice-slide-switch-spdt-repro test reproduces issue #247 at the netlist level.

David Montero f619a2cc7e feat(boards): expose Raspberry Pi 4 and Pi 5 in the picker (UI + pin wiring)
The BoardKind type and the QEMU backend already supported
raspberry-pi-4 (Cortex-A72) and raspberry-pi-5 (Cortex-A76) by reusing
the Pi 3 arm64 image set, but the frontend had no way to actually
select either: the board picker, the canvas renderer, the serial
monitor, the oscilloscope channel list, and the editor toolbar all
hard-coded "raspberry-pi-3" as the only Pi entry.  ComponentRegistry
even registered Pi 4 / Pi 5 metadata pointing at the velxio-raspberry-pi-3
custom-element tag — a placeholder that meant both boards rendered as
a Pi 3 in the picker thumbnail and on the canvas.

Add dedicated boards top-to-bottom:

  * `RaspberryPi4Element.ts` / `RaspberryPi5Element.ts` — Velxio-style
    schematic SVG (authored from scratch, not traced).  Pi 4 is the
    green PCB with BCM2711 SoC, 4× USB-A, USB-C power, dual µHDMI;
    Pi 5 is the darker green PCB with BCM2712 + RP1 southbridge,
    2.5 GbE, USB-C 5V/5A, PCIe FFC connector, dedicated power
    button.  Both carry a small "velxio" mark in the corner.

  * `pi40PinHeader.ts` — shared `buildPi40PinHeader()` helper that
    returns the 40-pin BCM layout.  Every Pi from the 1B+ onwards
    uses the same physical pin positions and same BCM GPIO
    assignment, so Pi 3 / Pi 4 / Pi 5 elements all consume this
    helper and example wires drawn against one model transfer to
    the others without re-routing.

  * React wrappers `RaspberryPi4.tsx` / `RaspberryPi5.tsx` render the
    custom elements at absolute positions (mirrors how
    RaspberryPi3.tsx handles the Pi 3 illustration).

  * Wire-up across the editor surface:
      - BoardOnCanvas: BOARD_SIZE entry + switch case.
      - BoardPickerModal: description, icon, kinds list.
      - ComponentPickerModal: thumbnails now instantiate the dedicated
        custom element (was velxio-raspberry-pi-3 fallback).
      - SerialMonitor / EditorToolbar: pill labels, icons, colours.
      - Oscilloscope: GPIO channel list (28 BCM pins).
      - SimulatorCanvas: remote-boards filter for run/stop sync.
      - SPICE boardPinGroups: same 5V / 3V3 / GND as Pi 3.
      - boardPinToNumber: accepts physical pin numbers ("1"-"40"),
        BCM names ("GPIO14") and power labels for any Pi 3/4/5 id.
      - ComponentRegistry: dedicated tagNames + per-board thumbnails
        (green for Pi 4, darker green for Pi 5).

  * EditorToolbar's Pi 3 special cases (Linux/Python compile path,
    Run/Stop routing) now use `isPiBoardKind()` so Pi 4 and Pi 5
    inherit the same behaviour automatically, and any future Pi
    family member (Zero / 1 / 2) lands in the right code paths the
    moment its backend boots.

QEMU backend was already wired (qemu_manager.py:71/82 + manifest entry
'raspberry-pi-3-virt' shared across arm64 Pis), so this commit makes
both boards selectable end-to-end without any backend follow-up.

David Montero Crespo 212ecd1bcb refactor: rename components and update prefixes to 'velxio-' for consistency
- Modified the index file to reflect the new naming convention for Velxio components.
- Changed JSX declarations to use 'velxio-' prefix for various components.
- Updated component overrides to replace 'wokwi-' with 'velxio-' for logic gates and other components.
- Adjusted SVG generation script to use 'velxio-' prefix for BMP280 and Raspberry Pi components.
- Marked submodules as dirty in QEMU and RP2040 libraries.
- Added .prettierignore and .prettierrc.json for consistent code formatting.
- Introduced InstrumentComponent with support for Voltmeter and Ammeter, including pin information handling.

davidmonterocrespo24 ed9911dcc3 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).

Reference plan: test/test_circuit/plan/phase_8_velxio_implementation.md
