test: add firmware loader tests with real compiled binaries
Tests for firmwareLoader.ts utility covering: Unit tests (44 tests): - Format detection (.hex, .bin, .elf by magic bytes and extension) - ELF architecture detection (AVR, ARM, RISC-V, Xtensa, big/little endian) - binaryToIntelHex round-trip through hexParser - ELF PT_LOAD segment extraction with synthetic and real ELF files - readFirmwareFile for all formats and board types Integration tests with arduino-cli compiled firmware: - AVR: .hex and .elf loaded into AVRSimulator, start/stop verified - RP2040: .bin and .elf loaded, base64 encoding verified - ESP32-C3: existing fixture .bin and .elf, RISC-V detection verified Cross-format compatibility: - .hex → AVR, .bin → RP2040, architecture mismatch warnings - File size limit enforcement (16MB max) All 663 tests pass (25 test files).

* Firmware Loader Tests
|

*
|

* Tests the firmwareLoader.ts utility with:
|
||||
* - Unit tests using synthetic data (format detection, ELF parsing, HEX conversion)
|
||||
* - Integration tests using real arduino-cli compiled binaries (AVR, RP2040, ESP32-C3)
|
||||
* - Cross-format compatibility tests
|
||||
* - Simulator loading tests (verify compiled firmware loads without crashing)
