Fix nil systemWideLogger panic on startup

systemWideLogger was called in main() before RunStartup() initialized it,
causing a nil pointer dereference in the logger goroutine. Initialize a
temporary stdout-only logger at the start of main() so all PrintAndLog
calls are safe; RunStartup() replaces it with the file-backed logger.
