lots of changes. new wshrpc implementation. unify websocket, web,
blockcontroller, domain sockets, and terminal inputs to all use the new
rpc system.
lots of moving files around to deal with circular dependencies
use new wshrpc as a client in wsh cmd
Adds resizability to the layout system.
Hovering in the margins of a block will highlight the available resize
handle and show a cursor indicating its resize direction. Dragging will
cause the resizing nodes to blur out and be replaced by an outline.
Releasing the handle will commit the new resize operation and cause the
underlying nodes to update to their new sizes.
We'll want to refactor this in the future to move all layout and resize
logic into a shared model that the TileLayout code can talk to, but
that's a future improvement. For now, this makes some compromises,
mainly that the logic is kind of distributed around.
