feat: implémentation complète du pipeline JA4 + Docker + tests

Nouveaux modules:
- cmd/ja4sentinel/main.go : point d'entrée avec pipeline capture→parse→fingerprint→output
- internal/config/loader.go : chargement YAML + env (JA4SENTINEL_*) + validation
- internal/tlsparse/parser.go : extraction ClientHello avec suivi d'état de flux (NEW/WAIT_CLIENT_HELLO/JA4_DONE)
- internal/fingerprint/engine.go : génération JA4/JA3 via psanford/tlsfingerprint
- internal/output/writers.go : StdoutWriter, FileWriter, UnixSocketWriter, MultiWriter

Infrastructure:
- Dockerfile (multi-stage), Dockerfile.dev, Dockerfile.test-server
- Makefile (build, test, lint, docker-build-*)
- docker-compose.test.yml pour tests d'intégration
- README.md (276 lignes) avec architecture, config, exemples

API (api/types.go):
- Ajout Close() aux interfaces Capture et Parser
- Ajout FlowTimeoutSec dans Config (défaut: 30s, env: JA4SENTINEL_FLOW_TIMEOUT)
- ServiceLog: +Timestamp, +TraceID, +ConnID
- LogRecord: champs flatten (ip_meta_*, tcp_meta_*, ja4*)
- Helper NewLogRecord() pour conversion TLSClientHello+Fingerprints→LogRecord

Architecture (architecture.yml):
- Documentation module logging + interfaces LoggerFactory/Logger
- Section service.systemd complète (unit, security, capabilities)
- Section logging.strategy (JSON lines, champs, règles)
- api.Config: +FlowTimeoutSec documenté

Fixes/cleanup:
- Suppression internal/api/types.go (consolidé dans api/types.go)
- Correction imports logging (ja4sentinel/api)
- .dockerignore / .gitignore
- config.yml.example

Tests:
- Tous les modules ont leurs tests (*_test.go)
- Tests unitaires : capture, config, fingerprint, output, tlsparse
- Tests d'intégration via docker-compose.test.yml

Build:
- Binaires dans dist/ (make build → dist/ja4sentinel)
- Docker runtime avec COPY --from=builder /app/dist/
