Investigate a debug option to run the Rust code as a web server to allow breakpoint debugging

[Keavon]

See if there's a way we can enable breakpoint debugging by setting up two paths for the architecture: the current wasm module, and a new web server approach. When optionally enabled while debugging, the Rust backend builds to native code and runs in the editor's debugger (with support for breakpoint stepping) and services requests over HTTP with the frontend. This would probably be of increased value as we delve further into backend work, like with Graphene node system and custom render engine development.
