Integrate Code Search with VS Code

In my submission for feature preview, I made a note about how searching Github is the primary way that I learn unfamiliar API's/languages and explore new ideas.

If I am thinking about writing a program to, IE, convert metadata from a relational database into a GraphQL AST, I typically do something like:

• Find the most popular libraries in the language for those two things
• Search for repos where both tools are present, and a keyword like convert* or *toGraphQL*
• Flip through pages of code results across repos, opening each file + repo in a new tab as I go if they seem promising

It would be fantastic to have this enhanced search experience built into my IDE, to prevent context-switches.

If possible, it would be great to eventually have a Jetbrains-compatible extension at some point too (like with Copilot) for the occasions when I need to work in a Jetbrains IDE.

Finally -- thanks for building this! It was sorely needed.
