- Replace scroll event listener with Intersection Observer in TableOfContentsRenderer
- Eliminates ~100ms forced reflows from offsetTop reads during scroll
- Revert Bootstrap CSS to blocking (media='all') - deferring caused CLS 0.954
- Keep CriticalBootstrapService available for future optimization
- Simplify CriticalCSSHooksRegistrar to only use CriticalCSSService

- Created CriticalCSSService (singleton) that queries BD directly in wp_head
- Service generates CSS BEFORE components render (priority 1)
- Renderers check is_critical flag and skip inline CSS if true
- Made generateCSS() public in Renderers for CriticalCSSService to use
- Removed CriticalCSSCollector pattern (timing issue with WordPress)
Flow:
1. wp_head (priority 1) → CriticalCSSService::render()
2. Service queries BD for components with visibility.is_critical=true
3. Generates CSS using Renderer->generateCSS() methods
4. Outputs: <style id="roi-critical-css">...</style>
5. When Renderers execute, they detect is_critical and omit CSS inline
