CCP Default Fund Cover-2 Sizing

Sizes a CCP default fund under the PFMI Principle 4 "Cover 2" standard: fund size must be at least the largest plus second-largest clearing-member stress loss across caller-declared stress scenarios. Applies each caller-declared scenario loss rate (in basis points, shaped from qfa-03-stress-test-engine's scenario_losses output as a chained input) to every caller-declared member exposure, ranks members per scenario, takes the two largest, and checks a caller-declared fund size against the worst scenario across the declared set. Not a stress-loss engine itself -- qfa-03 already computes multi-scenario portfolio stress losses; this node consumes that shape read-only and never reimplements it. Region-portable: no CCP, currency, or jurisdiction is hardcoded. Arithmetic sizing check only, no fund-size recommendation.
