 * [HERE]: modes/interactive/components/task-status-panel.ts - CC-style task status TUI panel
 *
 * Completed tasks stay visible (no auto-dispose) and are visually de-emphasized
 * via dim + strikethrough. Tasks that just transitioned to completed are
 * prioritized for the RECENT_COMPLETED_TTL_MS window so the user can see what
