fix(spoof): guard atomicWrite errors in updateTo

writeText and Files.move can throw IOException, SecurityException,
or AtomicMoveNotSupportedException. The exception previously
propagated through updateTo into BulletinPoller.fetchAndParse's
broad catch, which mislabelled it as "network_error" in the
history. Wrap atomicWrite, log the real failure, and return
before resetprop so the on-disk file and live props stay
consistent on failure.
