russell@unturf.com bca10f42a3 liquibase-0001: fix patch correctness + add unit test (4/4 PASS) 
- Corrected fix in patch: use persistent `seen` set (no backtrack remove)
  so diamond shared-nodes are visited once, not 2^D times
- Previous patch used DFS path-stack (cycle guard) which did not prevent
  the 2^D blowup for convergent diamonds
- Add unit test: chained-diamond D=12 shows 334× visit reduction (16381→49)
- Performance test: ArrayList→HashSet for evaluatedNodes gives 51× speedup at N=500
