 * Publicly exposed method to stop a running operation within the active group.

 * - Validates the operation belongs to the current group
 * - Prevents concurrent mutation using `lockedOperations`
 * - Aborts the operation's container execution
 * - Waits for full cleanup (exit/error + container teardown)
 * - Ensures promise is resolved before continuing
 *
 * Usage: await taskManager.stopTaskOperation(groupId, opId)
