Add complete BlackRoad OS backend API and wire all apps
- Created FastAPI backend with all endpoints (auth, agents, chat, blockchain, payments) - Added unified BlackRoad API client (blackroad-api.js) for all frontend apps - Updated index.html to use new unified API - Backend includes health checks, JWT auth, and mock AI responses - Ready for Railway deployment with Procfile and railway.json - All frontend apps can now share authentication and API calls 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
