Greatly improved JSViewer

Handle memory edges.  Color-coded edges & nodes to match lattice.
Add SB vs StringBuilder.  JSViewer needs SB to keep my sanity.
Catch successful peeps and `show` them.
Drop unused LLVM format, so I don't need to support Yet Another Printer.
SimpleWebSocket handles longer packets; more robust close.
Bug fix st/new fold.
Bug fix Phi pull-down op losing precision.
