TheFlow 2193b46a52 feat: add frontend pages for Tractatus demonstration platform
Implemented three core frontend pages using Tailwind CSS:

1. Homepage (index.html):
   - Hero section explaining framework value proposition
   - Three audience paths: Researcher, Implementer, Advocate
   - Framework capabilities showcase (6 core capabilities)
   - Te Tiriti acknowledgment in footer
   - Links to demos, documentation, and API

2. Documentation Viewer (docs.html):
   - Sidebar navigation with document list from /api/documents
   - Main content area with prose styling for technical docs
   - Automatic table of contents generation
   - Responsive grid layout (4-column on desktop)

3. Interactive Tractatus Demo (demos/tractatus-demo.html):
   - Four interactive demonstration tabs:
     * 27027 incident prevention (side-by-side comparison)
     * Live instruction classification (STR/OPS/TAC/SYS/STO)
     * Boundary enforcement examples (Tractatus 12.1-12.7)
     * Context pressure monitoring with interactive sliders
   - Real-time API integration with governance services
   - Visual comparison of WITH/WITHOUT framework behavior

All pages tested and operational with governance API endpoints.

<p class="text-blue-800">
The Tractatus-Based LLM Safety Framework implements <strong>architectural constraints</strong>
that ensure AI systems preserve human agency regardless of capability level. Instead of hoping
AI "behaves correctly," we build systems where certain decisions <em>structurally require</em>
human judgment.
