Cross-splice reports source length as transferred length.

Move a half-open slice from one deque to another at a valid gap. Reject overflow atomically. Return [source,destination,accepted,moved].
Why this case matters
Controlled bounded deque implementation model with explicit storage and lifecycle observations.
One recorded failure

|---|---|---|---|
| interior | [[4, 7], [14, 5, 6, 15], true, 4] | [[4, 7], [14, 5, 6, 15], true, 2] | Failed |
