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
- Add SynToCHMs timing field for behavioral detection
- Add AsyncBuffer configuration for output queue sizing
Architecture changes:
- Remove JA4Hash from LogRecord (JA4 format includes its own hash portions)
- Update api.TLSClientHello with new TLS metadata fields
- Update api.LogRecord with correlation, TLS, and timing fields
- Ensure 100% compliance with architecture.yml specification
Tests:
- Add unit tests for TLS extension extraction (SNI, ALPN, Version)
- Update tests for new LogRecord schema without JA4Hash
- Add tests for AsyncBuffer configuration

- Add PacketBufferSize field to api.Config struct
- Add DefaultPacketBuffer constant (1000 packets)
- Add JA4SENTINEL_PACKET_BUFFER_SIZE environment variable support
- Update mergeConfigs to handle PacketBufferSize override
- Update main.go to use configurable buffer size with fallback
- Update config.yml.example with packet_buffer_size option
Allows tuning for high-traffic environments by increasing buffer size
via config file or environment variable
