/**
 * Compact sidebar panel for todo status.
 *
 * Features:
 * - Shows todo progress and current task
 * - Width-aware rendering (compact at narrow widths)
 * - Real-data-friendly interface that InteractiveMode can wire later
 *
 * Usage:
 * ```typescript
 * const panel = new SidebarTodoPanel();
 *
 * // Update with data from InteractiveMode
 * panel.update({
 *   items: [
 *     { id: "1", content: "Implement feature X", status: "completed" },
 *     { id: "2", content: "Write tests", activeForm: "Writing test cases", status: "in_progress" },
 *     { id: "3", content: "Review code", status: "pending" },
 *   ],
 *   current: { id: "2", content: "Write tests", status: "in_progress" },
 *   totalCount: 3,
 *   completedCount: 1,
 * });
 *
 * // Render
 * const lines = panel.render(35);
 * ```
