Overhaul server to consolidate work methods into one function. Overhaul CLI to spin up server and request work instead of using its own puppeteer instance since testing found the server overhead to be negligible in comparison to puppeteer. Remove size getter from GL. Fix types and related imports. Add more environment variables to control server behavior. Add tests to server test script. Update package configuration files.
