OpenBSD developers rename pfsync packet header field to reduce false positive AI bug reports

A pfsync packet header field was renamed to eliminate misleading patterns that trigger automated AI bug report systems

The change aims to reduce noise in bug tracking systems caused by AI tools incorrectly flagging the original field name

This represents a practical solution to an emerging problem where AI systems generate false positive security issue reports

The modification maintains full functionality while improving the signal-to-noise ratio in project maintenance workflows
