Hey, that sounds really cool, and also sounds like it was a lot of work! As for point 2, we are planning at some point on making everything accessible via API and releasing a CLI, so a VSCode extension should definitely be possible.
Honestly, way less work than you'd think. A couple of months of a few hours per week tinkering. Copilot taught me the typescript and the vscode api is very powerful and well documented. Being able to leverage other extensions already doing the heavy work is a huge benefit (such as DVT for identifying symbol definitions).
