South town MVP: world sim, seasons, granary, contrast test + findings

Godot 4.7 C# world simulation per SPEC.md (with 2026-07-21 amendments).
15 NPCs, 5-state machine, demand-driven work, soul-imprint triad data
model, seasons with winter frost, granary, need-based gift economy,
selfish-soul contrast wiring, daily/per-villager/gift CSV logging.

FINDINGS.md documents the four soak experiments: the dead paradise,
the buffers winning, the emergent hungry gap, and the contrast test
proving the four-town thesis (and that selfishness wins until the
soul-consequence layer exists).
