Fix run-7 stone-lock collapse: construction outranks founding

Priority inversion fix: the homeless-gather-stone rule preempted all
communal work, so once everyone was homeless the town gathered stone
forever while half-built walls waited for wood that never came. Now
construction sites are first among works, homeless stone-gathering and
founding defer while any shelter is under construction, and granaries
require hunger memory + surplus (no more day-5 granary sprawl).
Run 7 logged in FINDINGS.md: in a needs-driven economy, priority
ordering is the constitution.

+## Run 7 — Organic construction v1: the stone-lock collapse
+
+**Setup:** two towns (South nature+selfish, North generational); all
+construction quotas removed. Shelters founded after three unsheltered
+nights (beds are real: 3 + modules); granaries founded from surplus.
+
+**Result:** a construction boom (8 shelters, multiple granaries by day
+10), then **total civilizational collapse by day 40** — every building
+ruined, and both towns spent the remaining 200 days homeless among the
+monuments. Cause: a priority inversion. The homeless-gather-stone rule
+preempted every other communal priority, so once ruins made everyone
+homeless, all communal souls locked onto stone forever — foundations got
+laid, walls (wood) never did, firewood hauling and granary stocking
+ceased entirely, and the emergency rule prevented the emergency from
+ever ending.
+
+**Lesson:** in a needs-driven economy, priority ordering *is* the
+constitution. An urgent rule that outranks the work needed to resolve it
+deadlocks the society. (Also: surplus-founding without scarcity memory
+produced granary sprawl by day 5 — buildings must be founded by lived
+need, not by momentary abundance.)
+
+**Fixes → run 8:** construction sites outrank homeless stone-gathering
+(finish the walls before founding another foundation); homeless founding
+defers while any shelter is under construction; granary founding
+requires hunger memory + surplus, not surplus alone.
