기능적 요구사항 및 비기능적 요구사항 정리

애플리케이션에 필요한 요구사항 리스트업

The issue asks for a list of functional and non-functional requirements for the application. No specific files, tests, or entry points are mentioned. To start, one would need to understand the project's purpose from the repository description and existing codebase. 'Done' would be a comprehensive requirements document, but the scope is undefined and requires significant design work.
