Changed

• nRF54H: The nrfutil device recover command now supports nRF54H.
• The logger now uses rolling file logging. The log filename has been changed to <command>.log. Each invocation of any command will append to its respective log file. Once exceeding a certain file size limit, the log will rollover to a new file with format <command>.<n>.log. A total of 5 rollover files are kept at most.
• Setting NRFUTIL_LOG_PREFIX no longer has an effect.
