// MARK: Functions
/// Calculates the number of tasks for a given task group using SwiftData.
/// Calculates the number of tasks for a given task group from an in-memory collection.
///
/// This method performs an efficient database-level count using SwiftData's `fetchCount` method with predicate-based filtering.
/// Tasks are categorized based on their due date and completion status.
/// This method filters the provided tasks array to count only those tasks that belong
/// to the specified group based on their due date and completion status. Tasks are
/// categorized as follows:
///
/// - **Completed**: Tasks with a non-nil `completed` date
/// - **Overdue**: Incomplete tasks due before today
/// - **Today**: Incomplete tasks due today (from start of day to end of day)
/// - **Upcoming**: Incomplete tasks due tomorrow or later
///
/// - Parameters:
/// - tasks: The array of tasks to filter and count.
/// - group: The task group to count tasks for.
/// - modelContext: The SwiftData model context to query.
/// - Returns: The number of tasks in the specified group, or 0 if an error occurs.
/// - Returns: The number of tasks in the specified group.
