Subject: Extract repl program from bild
This is basically building on top of bild's analysis, which is great becuase it
means that bild is becoming a useful tool rather than a monolithic do-everything
job runner. The eventual goal is for the bild analysis to be much more useful,
maybe even provide data to remote repls or language-server or whatever.
