feat: let opportunity helpers act autonomously

+The first bounded autonomous helper consumer is complete:
+
+- when an NPC becomes idle, `SimulationManager` re-derives the current helper
+  and passes that ephemeral result into ordinary action selection;
+- only the matching helper can select the reported gather/deposit action, and
+  starvation, critical hunger, mourning, low energy, sleep, and meal behavior
+  keep precedence;
+- the resulting task uses the existing definition, target resolver, finite-node
+  reservation, travel, extraction, inventory, and storage transaction paths;
+- no helper assignment, acceptance, reward, opportunity-specific event, or RNG
+  draw is added, while an in-progress ordinary task continues through the
+  existing NPC save fields and task-start history;
+- focused headless and Jajce runtime regressions prove autonomous selection,
+  precedence, finite-source targeting, reservation, and restore-time re-query.
+
+Milestone 7 is not complete. The immediate next slice should connect the
+existing one-hop fact transfer to this path: prove that a direct witness or
+performer can communicate an open need's exact trigger at a real shared
+activity, after which the newly informed trusted villager is re-derived as the
+helper and responds through the same autonomous selection contract. Keep this
+as a truthful event-reference transfer, not generic dialogue or multi-hop
+rumour infrastructure.
