Check whether a marimo notebook can run in a WebAssembly (WASM) environment — the marimo playground, community cloud, or exported WASM HTML.

Add "Open in molab" badge(s) linking to marimo notebooks. The badge can be added to any target: a GitHub README, documentation site, blog post, webpage, or any other markdown/HTML file.
