df3f04c10e revert: undo service badge filter, parser normalization, and SSH relay
Reverts commits 8c249f6, a6c7cfd, 7ff5703. The SSH log relay approach
requires container redeployment and doesn't retroactively fix existing
attacker profiles. Rolling back to reassess the approach.

7ff5703250 feat: SSH log relay emits proper DECNET syslog for sshd events
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).

a6c7cfdf66 fix: normalize SSH bash CMD lines to service=ssh, event_type=command
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.

bff03d1198 Add cross-decky correlation engine and decnet correlate command
When the same attacker IP touches multiple deckies, the engine builds a
chronological traversal graph and reports the lateral movement path.

decnet/correlation/
  parser.py   — RFC 5424 line → LogEvent; handles src_ip + src field variants
  graph.py    — AttackerTraversal / TraversalHop data types with path/duration
  engine.py   — CorrelationEngine: ingest(), traversals(), report_table/json,
                traversal_syslog_lines() (emits WARNING-severity RFC 5424)
  __init__.py — public API re-exports

decnet/cli.py — `decnet correlate` command (--log-file, --min-deckies,
                --output table|json|syslog, --emit-syslog)

tests/test_correlation.py — 49 tests: parser, graph, engine, reporting
