fix: optimize V2 UI (dark mode contrast, logic duplication, and functional deep-dives)

- Fixed dark mode visibility by setting proper text and tag luminosities in docs/static/v2_elite.css.
- Eliminated triple 'Explore Related' blocks by moving the injection outside recursion in src/v2_optimizer.py.
- Fixed 'Technical Deep-Dive' rendering by correcting Markdown indentation for collapsible blocks.
