- Relaxed RFC 5424 regex to accept either NILVALUE or a numeric PROCID; sshd / sudo go through rsyslog with their real PID, while syslog_bridge emitters keep using '-'. - Added a fallback pass that scans the MSG body for IP-shaped key=value tokens. This rescues attacker attribution for plain logger callers like the SSH PROMPT_COMMAND shim, which emits 'CMD … src=IP …' without SD-element params.
