Brian McGee 41f7ae08a8 feat(ui): enable storybook snapshot tests
- adds a process-compose namespace for running `storybook` and `luakit` together to replicate the `webkit`-based rendering that happens inside of `webview`
- adds some helper scripts for running storybook tests and updating snapshots, with documentation in the README.
- adds a `clan-app-ui-storybook` package which builds and tests the storybook, checking for rendering changes

Currently, we’re only doing markup-based snapshot tests. We’re also using headless chromium for the tests by default as I couldn't get webkit to work in the nix build.

As we’re only markup-based for the time being, this should be ok. But eventually I'd like to get it working with webkit.

// the #storybook-root element wraps the story. In Storybook 6.x, the selector is #root
const elementHandler = await page.$("#storybook-root");
const innerHTML = await elementHandler.innerHTML();
expect(innerHTML).toMatchSnapshot();
},
