Add linting/completion extensions

[BenCoffeed]

Required Functionality Ability for popular code editors to have completion, linting, and hints. I personally only care about VS Code. However, even having a CLI-based linter would be useful.

Proposed Solution

Use case Could reduce troubleshooting time on complex and large files where manually searching for errors could become tedious. Additionally, this will help in scenarios where errors may cause inaccurate/incomplete messages to appear.
