feat(ebpf): Apache HTTP capture + nginx multi-kernel validation
**Apache HTTP capture via apr_socket_recv** : - Uprobe sur libapr-1.so.0 (Apache Portable Runtime) - Compatible tous kernels 4.18+ (CentOS 8, Rocky 9/10) - Configuration unifiée : servers: ["nginx", "apache"] **nginx HTTP capture validation multi-kernel** : - Kretprobe __x64_sys_recvfrom validé sur CentOS 8 (4.18) - Rocky 9 (5.14) et Rocky 10 (6.12) confirmés - Contourne limitation tracepoint sys_exit_recvfrom **Documentation** : - docs/TEST_BUILD_STACK.md : stack complète test/build (VMs, Docker, RPMs) - services/ja4ebpf/docs/APACHE_HTTP_VALIDATION.md : validation Apache - services/ja4ebpf/docs/NGINX_MULTI_KERNEL_VALIDATION.md : validation nginx - docs/architecture.md + docs/services/ja4ebpf.md mis à jour **Tests unitaires Apache** : - internal/loader/apache_test.go : tests libapr, paths, structures BPF - internal/correlation/apache_test.go : tests corrélation HTTP Apache **Packaging** : - RPM spec mis à jour (version 0.3.0-1, changelog complet) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
