Fix #54: Performance optimizations - preload hero images

**#51** — Speaker Profile PDF exists and is linked ✓
- PDF at /downloads/Scott-Scoble-Human-Cultivation-Expert-Speaker-Profile.pdf
- Added download tracking

**#54** — Performance optimizations:
- Preload hints for hero images (responsive)
- Font preconnect optimized
- Moved font loading before other resources

**#55** — Umami event tracking added:
- hero-cta-book, hero-cta-explore (homepage)
- speaking-cta-book, speaking-download-pdf
- consulting-cta-schedule
