The Differences Between Archival and Full Nodes

In the future, we would want to support light clients as well. And for that, we would have to adjust our UTXL set commitment a bit. Currently, we are using UTXL, and UTXL cannot prove completeness. But that is definitely doable. Right? So let's just summarize those different things so people are clear.
