ESP32-C3 already uses the QEMU backend via Esp32Bridge, not browser-side
emulation. This adds MicroPython support by including C3 in the supported
set, adding the C3 firmware variant to the loader, and bundling the
fallback firmware binary.
Also fixes misleading type comments that said "browser emulation" for C3
boards — they actually use QEMU backend.

Extends MicroPython support (Phase 2) to ESP32 Xtensa boards running on
QEMU. Firmware is downloaded from micropython.org, cached in IndexedDB,
and loaded into QEMU. User code is injected via the raw-paste REPL
protocol after the MicroPython REPL boots.
- Create Esp32MicroPythonLoader.ts for firmware download/cache
- Add raw-paste REPL injection (Ctrl+A → Ctrl+E → code → Ctrl+D) to Esp32Bridge
- Extend loadMicroPythonProgram in store for ESP32 path
- Add ESP32 default MicroPython content (GPIO 2 blink)
- Simplify SerialMonitor Ctrl+C/D to work for all MicroPython boards
- Bundle fallback firmware for ESP32 and ESP32-S3
- Add all ESP32 board variants to SerialMonitor tab maps
Closes#3 (Phase 2)

builder (via littlefs-wasm), IndexedDB firmware caching
- Extend RP2040Simulator with loadMicroPython() method using USBCDC for
serial REPL instead of UART

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)
