8dd4c78b33 refactor: strip DECNET tokens from container-visible surface
Rename the container-side logging module decnet_logging → syslog_bridge
(canonical at templates/syslog_bridge.py, synced into each template by
the deployer). Drop the stale per-template copies; setuptools find was
picking them up anyway. Swap useradd/USER/chown "decnet" for "logrelay"
so no obvious token appears in the rendered container image.

Apply the same cloaking pattern to the telnet template that SSH got:
syslog pipe moves to /run/systemd/journal/syslog-relay and the relay
is cat'd via exec -a "systemd-journal-fwd". rsyslog.d conf rename
99-decnet.conf → 50-journal-forward.conf. SSH capture script:
/var/decnet/captured → /var/lib/systemd/coredump (real systemd path),
logger tag decnet-capture → systemd-journal. Compose volume updated
to match the new in-container quarantine path.

SD element ID shifts decnet@55555 → relay@55555; synced across
collector, parser, sniffer, prober, formatter, tests, and docs so the
host-side pipeline still matches what containers emit.

2dcf47985e feat: add HASSHServer and TCP/IP stack fingerprinting to DECNET-PROBER
Extends the prober with two new active probe types alongside JARM:
- HASSHServer: SSH server fingerprinting via KEX_INIT algorithm ordering
  (MD5 hash of kex;enc_s2c;mac_s2c;comp_s2c, pure stdlib)
- TCP/IP stack: OS/tool fingerprinting via SYN-ACK analysis using scapy
  (TTL, window size, DF bit, MSS, TCP options ordering, SHA256 hash)

Worker probe cycle now runs three phases per IP with independent
per-type port tracking. Ingester extracts bounties for all three
fingerprint types.

5585e4ec58 refactor: prober auto-discovers attackers from log stream
Remove --probe-targets from deploy. The prober now tails the JSON log
file and automatically discovers attacker IPs, JARM-probing each on
common C2 ports (443, 8443, 8080, 4443, 50050, etc.).

- Deploy spawns prober automatically (like collector), no manual targets
- `decnet probe` runs in foreground, --daemon detaches to background
- Worker tracks probed (ip, port) pairs to avoid redundant scans
- Empty JARM hashes (no TLS server) are silently skipped
- 80 prober tests (jarm + worker discovery + bounty extraction)
