fix(v1.1.13): socket ownership, correlation bugs, keepalive_seq

Socket Unix / systemd:
- RuntimeDirectory=logcorrelator dans logcorrelator.service : systemd
  recrée /run/logcorrelator avec logcorrelator:logcorrelator à chaque
  démarrage/restart, éliminant le problème de droits root:root
- Ajout de packaging/rpm/logcorrelator-tmpfiles.conf pour recréer le
  répertoire au boot via systemd-tmpfiles (couche de protection boot)
- Retrait de /var/run/logcorrelator du RPM %files et du %post
- Dockerfile.package : copie de logcorrelator-tmpfiles.conf dans SOURCES/

Corrélation — bugs:
- Fix CRITIQUE emitPendingOrphans : corruption de slice lors de l'expiration
  simultanée de plusieurs orphelins pour la même clé (aliasing du tableau
  sous-jacent, orphelins émis en double et fantômes persistants)
- Fix HAUT rotateOldestA : événement silencieusement perdu même avec
  ApacheAlwaysEmit=true ; retourne désormais *CorrelatedLog propagé dans
  ProcessEvent
- Fix MOYEN processSourceB (pending orphan path) : en mode one_to_many, le
  B event n'était pas bufferisé après corrélation avec un pending orphan A,
  cassant le Keep-Alive pour les requêtes A2+ sur la même connexion
- Fix BAS : suppression du champ mort timer *time.Timer dans pendingOrphan

Corrélation — observabilité:
- Ajout keepalive_seq (1-based) dans NormalizedEvent : numéro de requête
  dans la connexion Keep-Alive, incrémenté par processSourceA
- Tous les logs orphelins incluent désormais keepalive_seq=N
- keepAliveSeqA nettoyé automatiquement à l'expiration du TTL B

Tests: 4 nouveaux tests de non-régression (32 tests au total)

+- Fix: Unix sockets ne passent plus en root:root lors des restarts du service
+- Fix: Ajout de RuntimeDirectory=logcorrelator dans le service systemd (systemd gère /run/logcorrelator avec le bon propriétaire à chaque démarrage/restart)
+- Fix: Ajout de /usr/lib/tmpfiles.d/logcorrelator.conf pour recréer /run/logcorrelator au boot
+- Chore: Retrait de /var/run/logcorrelator du RPM %files (géré par tmpfiles.d)
+- Fix(correlation): emitPendingOrphans - corruption de slice lors de l expiration simultanée de plusieurs orphelins pour la même clé (slice aliasing bug, émissions en double)
+- Fix(correlation): rotateOldestA - l événement rotaté était perdu silencieusement même avec ApacheAlwaysEmit=true (retourne désormais le CorrelatedLog)
+- Fix(correlation): Keep-Alive cassé dans le chemin pending-orphan-then-B - le B event n était pas bufferisé en mode one_to_many, bloquant la corrélation des requêtes A2+ du même Keep-Alive
+- Chore(correlation): suppression du champ mort timer *time.Timer dans pendingOrphan
+- Feat(correlation): ajout de keepalive_seq dans les logs orphelins pour faciliter le debug (numéro de requête dans la connexion Keep-Alive, 1-based)
+- Test: 4 nouveaux tests de non-régression pour les bugs de corrélation

 * Thu Mar 05 2026 logcorrelator <dev@example.com> - 1.1.12-1
 - Feat: New config directive include_dest_ports - restrict correlation to specific destination ports
 - Feat: If include_dest_ports is non-empty, events on unlisted ports are silently ignored (not correlated, not emitted as orphan)
