feature: Code-Pathfinder online hosted sandbox playground

[shivasurya]

Description:

New playground (sandbox) to interact and execute Code-pathfinder (codeql) based queries and visualize the AST stuffs.

https://play.codepathfinder.dev 🎉

Few improvements that requires follow-up:

• Need to update the visualization graph after executing code-pathfinder query against the source code
• Able to share playground with unique link backed by some type of persistence like cloudflare KV store 🌤️
• Embed the playground in Rule atlas pages and able to execute queries + flag results

Checklist:

• Tests passing (gradle testGo)?
• Lint passing (golangci-lint run this requires golangci-lint)?
