Replaces generic "circuit breaker" with "Wiggum Break" — policy enforcement
halt condition named after Chief Wiggum (policy + Ralph Loop's dad).
Hard breaks (immediate halt) and soft breaks (finish then halt) with
wiggum.break event type. Updated both papers and shadow-detection skill.
Incorporate findings from literature survey: Six Sigma Agent (arXiv:2601.22290)
as the only prior explicit PM/OM-named framework, AgileCoder for Scrum sprints,
Reflexion as implicit PDCA, CAMEL for role theory.
