- Add data-segment-handle attribute to segment handle circles in WireLayer
- Skip long-press aiming timer when touch targets segment handle
- Add safety checks to cancel pending timer when segment drag starts
- Ensure segment drag always takes priority over crosshair activation
This fixes the bug where accidentally holding still while dragging a wire
segment would activate the crosshair overlay and interrupt the editing workflow.
- Snapshot-based undo/redo (full wires array per step, max 50 entries)
- Keyboard shortcuts: Ctrl+Z (undo), Ctrl+Shift+Z (redo)
- Toolbar buttons in canvas header (visible on mobile via separate
undo-controls CSS class that isn't hidden by mobile media query)
- All 4 wire mutations (add, remove, update, finish) push snapshots
- selectedWireId reset on undo/redo to avoid stale references
Two bugs fixed:
1. SaveProjectModal was reading from the legacy global `files` array instead
of the active board's file group, causing projects to be saved with the
wrong board_type (e.g. 'arduino-uno' for ESP32 projects).
Now reads from fileGroups[activeBoard.activeFileGroupId] and uses
activeBoard.boardKind for board_type.
2. Error handling was always showing "Save failed." — now shows:
- "Server unreachable. Check your connection and try again." for network errors
- "Not authenticated. Please log in and try again." for 401 responses
- The server's detail message (with status code) for other errors

Frontend WiFi detection via file-content scanning was unreliable because
fileGroups[board.activeFileGroupId] could be an empty array (not null),
bypassing the ?? fallback to editorState.files.
Fix: the ESP-IDF compiler now returns has_wifi:bool in its compile response.
The frontend stores this on the BoardInstance and uses it in startBoard()
instead of scanning file contents. The file-content scan is kept as a
fallback for boards that haven't been compiled in this session.

- handleRun now auto-compiles for ESP32/QEMU boards when no firmware is
available (same behavior as AVR/RP2040 boards)
- startBoard now reloads compiledProgram into the bridge if _pendingFirmware
was lost (e.g. after a page refresh between compile and run)
- Adds Esp32Bridge.hasFirmware() helper used by the store check

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)

Closes#14
- Right-click context menu on boards with "Remove board" option
- Delete/Backspace key removes the active board (when no component selected)
- Confirmation dialog before removal showing connected wire count
- Removing a board also removes all connected wires and cleans up
file groups, simulators, bridges, and VFS
- Cannot remove the last remaining board (button disabled + guard)

Closes#81
- Add `codeChangedSinceLastCompile` dirty flag to useEditorStore
- Play button now triggers compilation automatically when no compiled
program exists or code has changed since last compile
- Show compilation progress during auto-compile before run
- If compilation fails, show errors instead of running stale code
- Keep separate Compile button for manual compile-only workflow
- Play button always enabled (disabled only while running/compiling)
