/// Extension providing convenient initializers for fetching todos by group category.

/// This extension allows creating fetch descriptors that automatically filter and sort todos
/// based on their completion status and due dates according to the specified `TodoGroup`.
extension FetchDescriptor where T == Todo {
/// Creates a fetch descriptor for todos filtered and sorted by a specific group.
///
/// This initializer provides a convenient way to fetch todos categorized by their temporal
/// relevance and completion status. Each group applies appropriate predicates and sort orders:
///
/// - **Completed**: All tasks marked as done, sorted by completion date (most recent first)
/// - **Overdue**: Incomplete tasks with due dates before today, sorted by due date (most recent first)
/// - **Today**: Incomplete tasks due today, sorted by due date (earliest first)
/// - **Upcoming**: Incomplete tasks due after today, sorted by due date (earliest first)
///
/// - Parameters:
/// - group: The todo group category to filter by.
/// - calendar: The calendar to use for date calculations. Defaults to `.current`.
