Schema fix: all 9 claims from PR #3518 were missing type: claim and
description fields, causing tier0 validation failures. Added both.
Substantive: Minsky's FIH added as primary source to self-organized
criticality claim. The hedge→speculative→Ponzi progression IS the
mechanism that drives markets to the critical state. Three-framework
convergence section added (Bak + Mandelbrot + Minsky).
