[TASK] Create PRD and arc diagram for proposed team4 solution

[robertmitchellv]

🚧 What needs to be done

• Create a PRD that leverages the existing work for this project and its planning to dive a level deeper on the technical aspects of the requirements
• Create an architecture diagram that explains how the different interfaces, connections, and communication with the UI should work. There are some things we will have a good idea about and others that will be open questions. We need to clearly highlight where those open questions are.

🤔 Why it needs to be done

• Before selecting a technical implementation we're going to take a step back and ensure we have thought through the needs and requirements first. Given that the spirit of overhauling orchestration is in reducing complexity the raison d'etre here is to not prematurely trade complexity for complexity of another kind.

🏗️ Acceptance Criteria

• Given a technical consideration of solving problems with our tooling
• When we've correctly identified and explicated its requirements
• Then it is clearly laid out in a PRD and arc diagram

⚙️ Technical Notes

• PRD to be produced
• Arc diagram to be produced
