Features:
- Add local_ips configuration option for filtering traffic to local machine
- Auto-detection of local IP addresses (excludes loopback 127.x.x.x, ::1)
- Support interface 'any' for capturing on all network interfaces
- Add Linux SLL (cooked capture) support for interface 'any'
- Generate BPF filter with 'dst host' for local IP filtering
- Add LinkType field to RawPacket for proper packet parsing
Testing:

New features:
- Extract SNI (Server Name Indication) from TLS ClientHello
- Extract ALPN (Application-Layer Protocol Negotiation) protocols
- Detect TLS version from ClientHello using tlsfingerprint library
- Add ConnID field for TCP flow correlation
- Add SensorID field for multi-sensor deployments
