const size_t BOOTLOADER_OFFSET = 0x1000;

The current code does not include correct bootloader offsets for all MCUs.

According to https://github.com/espressif/arduino-esp32/blob/5521e02627fa6909818d7d12657b59814a506198/tools/pioarduino-build.py#L217-L219

board	bootloader offset
esp32	0x1000
esp32-S2	0x1000
esp32-S3	0x0000
esp32-C3	0x0000
upcoming boards

ESP32 classic was my main intention for the bootloader update as that's the only platform we are moving from V3 to V4

I don't recall now if the change of offset was one of the things Claude tried while trying to fix checksum errors for the other platforms

I'll have to give it a try, unless you beat me to it @softhack007
