fix(councilverse): repair quick-start and scaffold

[Victor "David" Medina (Victor-David-Medina)]

Summary

• Fix broken CouncilVerse quick-start examples and generated scaffold code to match the public formations API.
• Standardize OSS docs on 15 council presets and remove the unverified CAMP/arXiv claim.
• Lead README positioning with the differentiated "agents that disagree on purpose" wedge while keeping terms plain.

Verification

• npm run build
• npm run test (130 passed)
• node packages/create-councilverse/dist/index.js smoke-council + generated project npm install --ignore-scripts --no-audit --no-fund + npx tsc --noEmit
