100x faster, 100x smaller, and it runs in the browser!

The “tl;dr” is that we rewrote it (mostly) in Rust which compiles to WebAssembly for VS Code or the web, and to native binaries for Python. It’s over 100x smaller, over 100x faster, much easier to install & use, works fully in the browser, and is much more productive & fun for the team to work on.
