Sync works on the deployed site; add reproducible build and deploy script

The Pages deployment is now the primary copy, so two things had to change:

- Hosted pages fall back to steam-sync.py on 127.0.0.1:8765 instead of
  refusing to sync. steam-sync.py now answers Chrome's Private Network
  Access preflight (Access-Control-Allow-Private-Network), which is what a
  public https page needs before it may call into localhost.
- The build sources lived in /tmp and would have been lost. They now live in
  build/, and build.py outputs to the repo root. deploy.sh rebuilds,
  commits and pushes in one step.

Editing index.html directly is no longer the workflow - edit build/ and run
./deploy.sh.
