We now commit protocol.ts files during the roll.
New utils/roll_browser.js helps with that.
This makes our installation very shallow:
- build installer;
- download browsers.
We need to commit `package-lock.json` to repository to ensure
reproducible builds.
This also starts using [`npm ci`](https://docs.npmjs.com/cli/ci.html) to
install dependencies.
Drive-by: remove non-functioning `rebase` workflow.
