Associate metadata with terminals
...
This is a half-assed attempt at doing syntax coloring which I think
will almost certainly turn out to be insufficient. I'm committing it
just to record some of the work I've done but. BUT.
Probably trying to match tree-sitter is a better way of doing
this. (But, like, emitting tree-sitter grammars? Really? Wow, dude.
Way to give up.)

Specify and honor trivia tokens
...
e.g. "this is how machine-generated parsers know to skip blanks and
comments"
The run time implementation could be better; we don't really want to
just discard trivia because it's useful for e.g. doc comments and the
like. BUT for now this is fine.

Chaos: split tables, interactions, Terminal

nicer
- Token is renamed Terminal

Precedence now works for, like, resolving expressions in a single
big table but uh... it takes the time from 700ms to like 7s so I've
reverted it for now.
