검색 input  에  v-model="searchText" 처럼 v-model 양방향 데이터 처리를 해주고

다음과 같이 필터 함수 또는 computed  추가

   const searchText = ref("");
    const filteredTodos = computed(() => {
      if (searchText.value) {
        return todos.value.filter((todo) => {
          return todo.subject.includes(searchText.value);
        });
      }

      return todos.value;
    });

v-for="(todo, index) in filteredTodos"

v-for 목록 처리는  필터 처리된 filteredTodos 를 넣어주면 된다.
