 * Restarts a single operation (`opId`) within the currently running group (`group`).

 * This function is meant to be rebound to a `TaskManager` instance using `.bind(this)`, so it can
 * interact with all internal state and methods just like a native class method.
 *
 * The restart process:
 * - Aborts the operation's current execution
 * - Waits for its cleanup to complete
 * - Holds the group's completion to avoid premature advancement
 * - Re-executes the same operation within the current group
