pull, build, push

[ahdinosaur]

while i made a heap of progress, i never got this over the line before getting bogged down and losing momentum.

if i was to try this again, i think there's a much easier approach. rather than writing a complicated server that tries to do all of: listening for GitHub hooks, building when a hook is called, and hosting the files. i think this should instead focus on the build step only: pull the current repo directory from the server, perform the build, then push the resulting repo directory back to the server.

then the repo file hosting is nginx only, and the build step can become a GitHub action or TravisCI step or whatever.
