UI-facing half of the undo/redo feature. Combined with the previous two
commits, Ctrl+Z (or the toolbar button) now reverses every canvas
mutation: add/remove component, move, rotate, set property, add/remove
wire.
EditorPage.tsx:
- New window-keydown effect for Ctrl+Z / Ctrl+Y / Ctrl+Shift+Z (and the
Cmd equivalents). Uses the same input/textarea/contenteditable guard
as the existing Ctrl+S handler — Monaco's per-file undo and the AI
chat composer keep their own behaviour.
SimulatorCanvas.tsx:
- Two icon buttons (undo + redo) added to the canvas header, between
the board selector and the Serial Monitor toggle. Tooltip surfaces
the next command's description ("Undo: Add LED (Ctrl+Z)") so the
user knows exactly what's about to revert. Buttons disable when the
stack is empty in that direction.
- New `canvas-icon-btn` CSS class for square 32×32 icon-only buttons
(matches the visual weight of the existing Serial button without
the label).
- Subscribes to history / historyIndex via store selectors so the
buttons re-render reactively as commands are pushed/undone.
No new tests — the store-level coverage from 99ed22b already exercises
undo/redo round trips. UI affordances are wired pass-through to those
store APIs.

Replace arduino-cli with ESP-IDF 4.4.7 for ESP32 compilation — Arduino-compiled
firmware crashes in QEMU (9-28 reboots) while ESP-IDF boots cleanly (0 reboots).
The new espidf_compiler translates Arduino WiFi/WebServer sketches to native
ESP-IDF C code, compiles with cmake+ninja, and merges into 4MB flash images.
Key changes:
- ESP-IDF compiler: translates WiFi.begin/WebServer to esp_wifi/esp_http_server
- ESP-IDF project template with QEMU-optimized sdkconfig (DIO, 40MHz, no WDT)
- WiFi status parser for ESP-IDF serial logs (wifi_status, ble_status events)
- IoT Gateway HTTP reverse proxy for ESP32 web servers
- WiFi/BLE auto-detection from sketch content + visual status icons
- Static IP 192.168.4.15 matching slirp DHCP first-client range
- Docker: new espidf-builder stage with ESP-IDF 4.4.7 toolchain
- 157 tests covering WiFi/BLE for both ESP32 (Xtensa) and ESP32-C3 (RISC-V)
