giles 43fa31375d datalog: magic-vs-semi work-shape test on chain-12 (209/209) ...

Demonstrates the practical effect of goal-directed evaluation:
chain of 12 nodes, semi-naive derives the full ancestor closure
(78 = 12·13/2 tuples), while a magic-rooted query at node 0
returns only its 12 descendants. Concrete check that magic
limits derivation to the query's transitive cone.
