New log_relay.py replaces raw 'cat' on the rsyslog pipe. Intercepts
sshd and bash lines and re-emits them as structured RFC 5424 events:
login_success, session_opened, disconnect, connection_closed, command.
Parsers updated to accept non-nil PROCID (sshd uses PID).
The SSH honeypot logs commands via PROMPT_COMMAND logger as:
<14>1 ... bash - - - CMD uid=0 pwd=/root cmd=ls
These lines had service=bash and event_type=-, so the attacker worker
never recognized them as commands. Both the collector and correlation
parsers now detect the CMD pattern and normalize to service=ssh,
event_type=command, with uid/pwd/command in fields.
