Done

It feels like we're mixing a lot of different things together:

• General Ticket/PR processes
• DoD for a feature - related to reviewing PRs
• DoD for a release - related to release management and QA process
• DoD for the project - related to a project setup and checklist

I think these should be split up into clear sections.
