Initial commit: RouteWatch BGP stream monitor

- Connects to RIPE RIS Live stream to receive real-time BGP updates
- Stores BGP data in SQLite database:
  - ASNs with first/last seen timestamps
  - Prefixes with IPv4/IPv6 classification
  - BGP announcements and withdrawals
  - AS-to-AS peering relationships from AS paths
  - Live routing table tracking active routes
- HTTP server with statistics endpoints
- Metrics tracking with go-metrics
- Custom JSON unmarshaling to handle nested AS sets in paths
- Dependency injection with uber/fx
- Pure Go implementation (no CGO)
- Includes streamdumper utility for debugging raw messages
