feat: load precompiled firmware files (.hex, .bin, .elf) directly
Closes #1
Add the ability to upload precompiled firmware files directly into the
emulator, bypassing the built-in compilation step. This enables users
with custom toolchains (ESP-IDF, PlatformIO, ASM workflows) to use
Velxio purely as an emulation/debugging environment.
New features:
- "Upload firmware" option in the overflow menu (accepts .hex, .bin, .elf)
- Automatic format detection from file extension and magic bytes
- ELF parser extracts PT_LOAD segments and detects target architecture
(AVR, ARM, RISC-V, Xtensa) from ELF e_machine header
- Architecture mismatch warnings logged when ELF target differs from
current board (non-blocking — upload proceeds anyway)
- Firmware routed to the correct simulator loader via existing
compileBoardProgram() — no simulator changes needed
Supported formats per board:
- AVR (Uno/Nano/Mega/ATtiny85): .hex (direct), .elf (parsed → HEX)
- RP2040 (Pico): .bin (direct), .elf (parsed → binary)
- ESP32-C3: .bin (direct), .hex, .elf (parsed → binary)
- ESP32/S3 (QEMU): .bin (direct), .elf (parsed → binary)
