chore: update templates and development documentation
...
- templates/sniffer/decnet_logging.py: add logging configuration for sniffer integration
- templates/ssh/decnet_logging.py: add SSH service logging template
- development/DEVELOPMENT.md: document new MySQL backend, p0f, profiler, config API features
- pyproject.toml: update dependencies for MySQL, p0f, profiler functionality

feat: JA4/JA4S/JA4L fingerprints, TLS session resumption, certificate extraction
...
Extend the passive TLS sniffer with next-gen attacker fingerprinting:
- JA4 (ClientHello) and JA4S (ServerHello) computation with
supported_versions, signature_algorithms, and ALPN parsing
- JA4L latency measurement via TCP SYN→SYN-ACK RTT tracking
- TLS session resumption detection (session tickets, PSK, 0-RTT early data)
- Certificate extraction for TLS ≤1.2 with minimal DER/ASN.1 parser
(subject CN, issuer, SANs, validity period, self-signed flag)
- Ingester bounty extraction for all new fingerprint types
- 116 tests covering all new functionality (1255 total passing)

feat: Phase 1 — JA3/JA3S sniffer, Attacker model, profile worker
...
Add passive TLS fingerprinting via a sniffer container on the MACVLAN
interface, plus the Attacker table and periodic rebuild worker that
correlates per-IP profiles from Log + Bounty + CorrelationEngine.
- templates/sniffer/: Scapy sniffer with pure-Python TLS parser;
emits tls_client_hello / tls_session RFC 5424 lines with ja3, ja3s,
sni, alpn, raw_ciphers, raw_extensions; GREASE filtered per RFC 8701
- decnet/services/sniffer.py: service plugin (no ports, NET_RAW/NET_ADMIN)
- decnet/web/db/models.py: Attacker SQLModel table + AttackersResponse
- decnet/web/db/repository.py: 5 new abstract methods
- decnet/web/db/sqlite/repository.py: implement all 5 (upsert, pagination,
sort by recent/active/traversals, bounty grouping)
- decnet/web/attacker_worker.py: 30s periodic rebuild via CorrelationEngine;
extracts commands from log fields, merges fingerprint bounties
- decnet/web/api.py: wire attacker_profile_worker into lifespan
- decnet/web/ingester.py: extract JA3 bounty (fingerprint_type=ja3)
- development/DEVELOPMENT.md: full attacker intelligence collection roadmap
- pyproject.toml: scapy>=2.6.1 added to dev deps
- tests: test_sniffer_ja3.py (40+ vectors), test_attacker_worker.py,
test_base_repo.py / test_web_api.py updated for new surface
