Implémente le pendant serveur du DTLSHandlerComponent d'UE (la pile client est
[DTLS, Stateless]) : le client exige un DTLS en mode PSK dont l'identité = user_id.
- DtlsPskStore : table user_id -> PSK 32o, chargée depuis l'env (PROSPECT_DTLS_PSKS,
rendu Vault) — aucune clé en dur ni commitée.
- DtlsPacketTransport : pont entre l'API bloquante DTLS de BouncyCastle et le modèle
paquet-par-paquet du PacketHandler (handshake sur thread dédié).
- ProspectPskTlsServer : serveur DTLS-PSK BouncyCastle (DTLS 1.2, identité=user_id).
- DTLSHandlerComponent : composant du pipeline (Incoming déchiffre / Outgoing chiffre),
activé au NMT_Hello portant un EncryptionToken.
- UWorld.NotifyControlMessage : sur NMT_Hello chiffré, si la PSK de l'identité est
connue -> NMT_EncryptionAck + BeginHandshake ; sinon warning (comme avant).
Compile (0 erreur, BouncyCastle 2.4). ⚠️ Le framing exact DTLS-sur-PacketHandler et
le routage des records de handshake demandent une ITÉRATION EN LIVE contre le vrai
client (invalidable hors client).
Bit-decoded real client packets: the header is 65 bits (not stock UE 4.27's 64).
One extra bit sits between the ack history and the packet-info payload; consuming
it realigns bHasPacketInfoPayload + jitter + bHasServerFrameTime, and the first
control-channel bunch parses (ChIndex 0, open, reliable = NMT_Hello).

Log + drop the packet (with net version) instead of throwing, so a
bit-alignment/version mismatch with the client doesn't kill the server.

The Cycle client does not derive its initial packet sequences from the
handshake cookie the way stock UE does (its acked server-seq isn't present
anywhere in the cookie), so the cookie-based InitSequence disagreed and
every post-handshake packet was rejected as out-of-order. On the first
packet, adopt the client's announced Seq/AckedSeq instead.

R&D branch for an authoritative Unreal game server (Prospect.Unreal).
The connection handshake already reaches PlayerController spawn; this
commit pushes it toward real players joining:
- Program.cs: target the Cycle station map + game mode (configurable via
PROSPECT_MAP/GAMEMODE/PORT), proper host loop, and initialise a
GameSession so NMT_Join -> Login no longer fails ("GameSession is null").
- UWorld.WelcomePlayer: send the world's real map/game mode to the client
instead of the UE ThirdPerson template.
- Dockerfile.gameserver + .gitea/workflows/game-server.yml: build/push a
separate image (the-cycle-game) on the game-server branch, ntfy notify.
- GAMESERVER.md: honest state + roadmap (player spawn + movement
replication need live client testing; AI/loot intentionally deferred).
