feat(provider): enable DevIn agent responses #101

This commit enables the execution of DevIn agent responses within the custom agent chat processor by adding a new interface for DevIn response providers and implementing a custom agent response provider for DevIn language. The DevIn custom agent response provider executes the DevIn code and notifies the project of the result.
