fix(adt): scrub NaN/inf floats at write time

Browse source 
ADTWriter::writeFloat now coerces non-finite values to 0 before
emitting bits, so a stray NaN in a chunk position, MDDF rotation,
or MODF extent can't leak into the saved ADT and produce invisible
terrain or off-map placements after reload.
