docs(examples): add builder-adversary-deferred — verify after a long segment

Coarsest review cadence: the Builder self-certifies the build phases and the
Adversary does ONE comprehensive cold-verification of the whole accumulated build
in a final `review` phase (vs orig per-phase, lean per-gate). Full original
prompts + a DEFERRED REVIEW CADENCE override, so it isolates verification cadence.
Cheapest coordination; the trade-off is the independent check arrives late (late
rework risk + self-certification drift on build phases). README spells it out.

+# examples/builder-adversary-deferred — Adversary verifies ONCE, after a long segment of building.
+#
+# Same pattern + full original prompts as ../builder-adversary, but the REVIEW CADENCE is coarsest:
+#   • lean      = the Adversary verifies per gate (finest)
+#   • orig      = the Adversary verifies per phase (medium)
+#   • deferred  = the Adversary verifies ONCE, comprehensively, after the whole build (coarsest)
+# The Builder SELF-CERTIFIES the build phases (wc, json) to advance; the Adversary stays out until the
+# final `review` phase, where it cold-verifies the ENTIRE accumulated calculator in one pass. Cheapest
+# coordination, but the independent check arrives late (see README for the trade-off).
