docs(architecture): package map reflects the io/format/flow extraction

Adds the io package row (IoSubsystem/Channel/FileHandle/DosPaths/
QbBinaryCodec), lists PrintFormat/Jumps/LabelSearch under interp, and
fills in the previously undocumented machine and capture packages.
The audio row no longer claims "no audio yet".
