[FEATURE] Terminal Kanban — lightweight terminal Kanban board

I want to build a A small, dependency-light terminal Kanban board for managing personal tasks. Use it entirely from the command line to create boards, add cards, move cards between columns (Todo, In Progress, Done), tag/prioritize cards, and persist boards to disk. The project is beginner-friendly and ideal for Hacktoberfest contributions. .Please assign me this under the tag of Hacktoberfest

No implementation files, entry points, or tests are named. Start by reviewing the repository's existing project conventions, then determine how the command-line board should create boards, manage cards and columns, tag or prioritize cards, and persist data; done means all listed operations work from the terminal and survive being saved to disk.
