Skill and tooling fixes from @rudycelekli: corrected platform facts, sounder math in the finance and testing guidance, and validator fixes.

• Platform facts:
  • schema (2.0.1 → 2.0.2): FAQ rich results ended in 2026, and HowTo and the sitelinks search box were retired earlier; Schema.org vocabulary is now kept separate from what Google displays (#767).
  • analytics (2.0.2 → 2.0.3): GA4 enhanced-measurement event names in reports (#774), and localized price text kept out of monetary tracking (#779).
  • churn-prevention (2.0.1 → 2.0.2): correct Paddle Billing dunning webhook events (#776).
  • aso (2.0.1 → 2.0.2): Google Play preview videos can autoplay muted (#784).
  • seo-audit (2.1.0 → 2.1.1): preferred canonicals for same-language regional duplicates, which must sit inside the hreflang cluster (#782).
  • directory-submissions (2.1.0 → 2.1.1): verify the actual link and its rel qualifiers rather than HTTP headers (#768).
• Math and reasoning:
  • ab-testing (2.0.0 → 2.0.1): correct p-value and confidence-interval interpretation for fixed-horizon tests (#769).
  • ads (2.4.5 → 2.4.6): CAC payback uses gross margin and cohort recovery, keeping firm verdicts (#773). The Meta Andromeda playbook moved into references/meta-andromeda-playbook.md, bringing SKILL.md under 500 lines.
  • marketing-plan (1.2.0 → 1.2.1): ARR budgets account for churn in the starting base (#772).
  • pricing (2.1.2 → 2.1.3): Van Westendorp measures price perception, not demand (#771).
  • referrals (2.0.2 → 2.1.0): rewards are capped by total CAC (#780). A new references/affiliate-operations.md covers cohort economics, partner activation, payout policy, and incrementality; it builds on @Adi29102000-s's contribution in #417 (#724).
  • attribution (1.1.2 → 1.1.3): stale booking-link identity is cleared (#770), and webhook analytics failures are non-fatal (#778).
• Routing and creative:
  • cro (2.0.1 → 2.0.2) and emails (2.1.2 → 2.1.3): a routing table that sends each question to the right reference (#699).
  • ai-seo (2.7.4 → 2.7.5): question-level routing to its references (#702).
  • ad-creative (2.9.4 → 2.10.0): headline treatments by buyer awareness stage (#727).
• Tooling: the validator and sync script now handle Windows line endings (#709), ignore indented metadata keys (#763), keep literal $ text (#764), and require frontmatter that opens and closes the file (#762).
