[B] Refactor AdoptOrOrphan job

* Add uniqueness to the job to prevent multiple adoptions for a single
  annotation
* Add cyclical detections and execution time limits
  * Restrict an attempt to locate the character positions from
    iterating endlessly
  * Monitor execution time on various iterations / recursions and
    bail out if it is taking too long
* Any bailout action will orphan the annotation
