entry.sh stops the judge swarm after three cycles despite the documented convergence behavior #297

The README says that judges run in cycles until no new facts are produced, but entry.sh:32 hard-codes --max-cycles=3. A swarm whose rules need a fourth cycle silently stops with an incomplete factbase, even though the documented execution model promises convergence.

A chain such as A -> B -> C -> D needs four update cycles: the first creates B, the second C, the third D, and the fourth confirms that no new facts remain. The current entry point exits after the third cycle and leaves D missing.

Either let judges update run to its normal fixed point or expose/validate a cycle limit and document the bounded behavior. Add a fixture with a dependency chain longer than three cycles so the entry point cannot report success with incomplete output.
