* Ring buffer implementation:

* - queue_front_ points to the next item to execute (read position)
* - Buffer size is max_queued_ (the maximum number that can be queued)
* - Write position is calculated as: (queue_front_ + num_queued_) % max_queued_
* - When an item finishes, queue_front_ advances: (queue_front_ + 1) % max_queued_
* - Buffer size is max_runs_ - 1 (max total instances minus the running one)
* - Write position is calculated as: (queue_front_ + num_queued_) % (max_runs_ - 1)
* - When an item finishes, queue_front_ advances: (queue_front_ + 1) % (max_runs_ - 1)
* - First execute() runs immediately without queuing (num_queued_ stays 0)
* - Subsequent executes while running are queued starting at position 0
