💡 What: Lifted portfolioStats(domains) and worstDomain(domains) calculations to the top level renderDashboardPage and passed the result down to renderDashboardHero and renderDashboardStatStrip.

🎯 Why: Previously, renderDashboardPage, renderDashboardHero, and renderDashboardStatStrip each independently iterated over the entire domains array to compute the same statistics, causing redundant O(N) penalties during every dashboard render.

📊 Impact: Reduces array iteration passes over the domains array during dashboard render from up to 5 to exactly 2, significantly reducing CPU cycles and GC pressure for large domain portfolios.

🔬 Measurement: Verified using the full test suite (pnpm test); all 860 tests passed.

Lifted calculations of portfolio stats and worst-performing domain to the top level of `renderDashboardPage` and passed them down to sub-components `renderDashboardHero` and `renderDashboardStatStrip`. This eliminates redundant O(N) array iterations over the `domains` array during a single dashboard render cycle.
