feat: create Lux website with sleek/noble aesthetic

Website design:
- Translucent black (#0a0a0a) with gold (#d4af37) accents
- Strong serif typography (Playfair Display, Source Serif Pro)
- Glass-morphism cards with gold borders
- Responsive layout with elegant animations

Content:
- Landing page with hero, code demo, value props, benchmarks
- Effects-focused messaging ("No surprises. No hidden side effects.")
- Performance benchmarks showing Lux matches C
- Quick start guide

Technical:
- Added HTML rendering functions to stdlib/html.lux
- Created Lux-based site generator (blocked by module import issues)
- Documented Lux weaknesses discovered during development:
  - Module import system not working
  - FileSystem effect incomplete
  - No template string support

The landing page HTML/CSS is complete and viewable.
