task: add detailed mermaid flow diagram to the readme #64
Description
This issue tracks work to add a detailed mermaid flow diagram to the main README. The core flow that should be documented can be found in lib/hooks/app/api.rb. It should account for handlers, auth plugins, lifecycle plugins, etc. More context around how the whole service works can be found in the docs/* directory. Much of the source code should be inspected when designing a detailed request flow diagram and it should be mermaid style.
