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)
