Adds CommonPackets (ServiceType::COMMON): ClientVersionConfirm (the client's handshake, with the handler that logs it and answers), ServerVersionConfirm, DisconnectNotify and GeneralNotify (layout from the 1.10.64 client's PacketHandler_MSG_SERVER_GENERAL_NOTIFY; DLU does not send it yet). AuthPackets::LoginRequest reads the login and keeps the old login logic in its Handle; ClientPackets::LoginResponse (with the Stamp list) replaces the hand written response, and AuthPackets::SendLoginResponse fills it from the settings as before. dServer::Disconnect writes a DisconnectNotify. AuthServer's if-chain and WorldServer's COMMON case become CommonPackets::Handle / AuthPackets::Handle, dispatch maps that read the struct, drop and log it if it does not deserialize, then Handle. HandleHandshake and SendHandshake are gone. No wire change. Verified against a frozen verbatim copy of the old functions (tests/dGameTests/dNetTests/Legacy): the old handshake and login handlers and the new dispatchers are fed the same packets and must send identical bytes to the same address (same RNG seed for the session key), over grids of versions, service types, ports, response codes, error messages, IPs and stamp lists; plus hand computed golden bytes, round trips, truncation checks, and a deliberate field width mutation that made the tests fail. The only behaviour difference: truncated handshake and login packets are now dropped instead of handled with whatever was read. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
