* KMP [FirmwareUpdateHandler] for nRF52 devices.
*
* Despite its historical name, this handler now drives **both** Nordic Secure DFU (service `FE59`) and Nordic Legacy
* DFU / Adafruit `BLEDfu` (service `1530`). After triggering the buttonless reboot it sniffs which DFU service the
* bootloader exposes and dispatches to the matching [DfuUploadTransport] implementation.
*
* All platform I/O (zip extraction, file reading) is delegated to [FirmwareFileHandler].
