Add a frontend interface

[rafe-murray]

Summary

This project is currently hard to use, requiring users to understand and write in C++ source code, then compile and run it themselves.

Desired Outcome

An intuitive UI/UX that provides sleek visual components, fast response times, keyboard shortcuts and drag and drop edits that allows a user to create and modify a circuit before solving it.

Plan

1. Expose the circuitGraph functionality as a native Node module. To create a circuit, we could either expose the mutator methods through the Node API or pass a json string and parse it.
2. Create the client-side circuit drawing functionality. We could use diagram.js to develop a custom circuit editor (see here for better documentation). Vibe coding might also be well-suited to this task.
3. Connect the two. This would look something like a web app that uses whatever client-side interface we create and then does some processing server-side to create the circuitGraph from what the user created, then solves the circuit and updates the UI accordingly.
