Add MRD Viz scaffold

[ccapetz]

vs code extension template built with yo code in mrd-viz/extension

previous basic backend logic (cli, html harness, stage 1 logic) ported into mrd-viz/backend

todo is linking the two and exploring vs code extension dev guides to see how i want to implement double clicking, file inpsection, webview ui, etc.

as we talked about yesterday, we dont yet want to merge these changes into main - we want to have a base branch where we can merged staged changes and then merge that into main once all the functionality is ready. You select the branch you merge into when you create the PR, if you already made a base branch go ahead and switch it up top.

also, is there a way for me to run this template scaffold somehow as a local extension? or is it not ready for that kind of test yet?

created the base branch and connected the prs (71 and 72) to it, not main.

yeah the extension template is runnable, in the extension project you can just hit f5 to open a new window (extension development host) and then in there you can run commands in the command palette (Hello World) and there should be a notification popup that says "Hello World from MRD Viz! Testing..."
