Create a dry run feature

[JesseAbram]

Allowing the runtime to be run in the browser would create a dry run feature that can be shipped and useful for checking that configs and aux data work for programs to be used.

This would mitigate users inputting incorrect fields and having to re set the configs (also would help in the programs side but that doesn't need to be done in the browser so is definitely easier and arguably already exists)

If we aren't able to run the runtime in the browser a third party api solution is possible but less ideal
