Add simple error handling
...
Now we don't have to deal with a completely obliterated terminal every time
something breaks! \o/

Refine behavior of next-node
...
I originally thought next-node should wrap around to the next sibling of the
parent node, but actually playing with the navigation showed that what
I *actually* wanted was for it to go to the first child in the absence of a
next sibling.

Disallow the root node from becoming point-node
...
Unless it's the only node, anyway. This fixes the issue of not being
able to navigate across the children of the document root without
first doing a down-node.

Extremely rudimentary tree navigation
...
Needs some error checking, and we want to only consider named nodes so
we're navigating the abstract tree rather than the tree of all tokens.

Add state structure
...
As we expand with new features and get tree-sitter working, we're
going to have more to keep track of than can reasonably be done with
individual arguments. Guile's modified srfi-9 lets us do this in a
nice functional style.
This also subtly tweaks the behavior of character insertion so it's
actually correct.
