A TUI todo app. Single file, standard lib only. Navigate items with arrow keys and manage them via vim-style commands prefixed with :

• :a / :add <text> — Add item
• :p / :pin <item index> — Pin item to the top and animate it with amber→red gradient
• :rm <item index> — Remove item (requires confirmation)
• :q — Quit

All data persists to a SQLite database in ~/.todo/todo.db.
