Update the README to reflect the fourth interim delivery, where the project should be considered finished, including testing. The README should be updated with: - Current and completed functionality. - Updated setup and run instructions. - Current frontend, backend and database setup. - Testing strategy and what has been tested. - Instructions for running the tests. - Current accessibility and sustainability considerations. - Updated documentation of AI usage. - Known limitations or remaining issues, if any. - Any changes made since the third interim delivery. - Remove or update outdated information from earlier deliveries. The goal is for the README to describe the project as a complete solution that is ready for peer review, while still allowing for smaller changes and improvements afterwards.
