Fixed potential use-after-free in Update() when gcRound deletes
a session between GetOrCreate() and acquiring the session lock.
Changes:
- Add 'deleted' flag to SessionState
- Mark sessions as deleted before removing from map in gcRound
- Check deleted flag in Update and recreate session if needed
This ensures updates to deleted sessions create a new session
instead of modifying a freed/dangling reference.

Add uprobe_ssl_write_entry/uretprobe_ssl_write_exit to capture server HTTP
responses via SSL_write with direction=1. Implement full HPACK decoder
(RFC 7541 static table, multi-byte integers, literal representations) for
HTTP/2 header extraction. Add AcceptCache mapping {tgid,fd}→SessionKey
from accept4 events as authoritative source for SSL correlation when BPF
ssl_conn_map has src_ip=0. Add ip_total_length to tcp_syn_event BPF struct.

Add run-e2e-test.sh with CLI parameters (--hits, --http-ratio, --dns, --tls,
--src-ips, --keep-analysis, --up) for configurable traffic generation. Traffic
runs from VM endpoints with multiple source IPs (alias IPs on eth0) to produce
distinct sessions for the ML pipeline. Fix curl TLS flags (--tlsv1.2 instead
of --tls-v1-2), skip redundant local verification in distributed mode, and
fix dashboard is_available() cache that never retried after ClickHouse recovery.

- Dockerfile.package: migre go-builder de golang:bookworm (Debian) vers
rockylinux:9, installe Go depuis le tarball officiel, remplace apt par
dnf (clang llvm libbpf-devel bpftool)
- Suppression du champ 'correlated' de l'agent ja4ebpf : avec eBPF/XDP,
la corrélation L3/L4↔L7 est toujours implicite par présence des champs.
Supprimé de : session.go, manager.go, main.go (x5), clickhouse.go
- Thèse (6 corrections listées + cohérence correlated) :
1. §3.5 + §3.9.1 : SSL_read retourne des octets bruts sans respecter les
frontières H2 → buffer circulaire de réassemblage en Go userspace
2. §3.1 : supprimé libpcap + CAP_NET_RAW, remplacé par définition uprobe
3. §4 + §7 : compte exact 96 features en 8 familles (Famille 1–8),
supprimé taxonomie F1–F11 obsolète, tous les totaux mis à jour
4. §2.4 + §8 : remplacé 7 fausses URLs arXiv par [Référence à vérifier]
5. §4 Famille 2 : ja4_drift_ratio → renvoi à Famille 8 (définition complète)
6. §6.4 : ajouté limite 'Overhead de l'uprobe SSL_read'
+ §3.6 : supprimé correlated=0/1 du texte architectural
