Add Claude Router to docker-configs

Integrate Claude Router v1.1.0 as a new service in the main docker-compose stack:

Features:
- Smart API router with automatic failover between Claude Pro and Claude API
- Scheduled health checks every hour (0-4 minutes) to detect quota recovery
- Intelligent auto-switch back to Claude Pro when available
- Manual health check endpoint for immediate testing
- Complete documentation and Docker containerization
- Compatible with Claude Code CLI

Changes:
- Add router/ subdirectory with complete Claude Router project
- Integrate claude-router service into main docker-compose.yml
- Resolve port conflict (move SillyTavern to 8002, Claude Router uses 8000)
- Update .gitignore for router-specific exclusions

The router automatically detects when Claude Pro quota is restored
and switches back to prioritize the premium service.
