fix: correction race conditions et amélioration robustesse

- Correction race condition dans tlsparse avec mutex par ConnectionFlow
- Fix fuite mémoire buffer HelloBuffer
- Ajout rotation de fichiers logs (100MB, 3 backups)
- Implémentation queue asynchrone avec reconnexion exponentielle (socket UNIX)
- Validation BPF (caractères, longueur, parenthèses)
- Augmentation snapLen pcap de 1600 à 65535 bytes
- Permissions fichiers sécurisées (0600)
- Ajout 46 tests unitaires (capture, output, logging)
- Passage go test -race sans erreur

Tests: go test -race ./... ✓
Build: go build ./... ✓
