feat: ZMMO client base (Game/Entity|Controller|Modes|Network)

Estrutura inicial do cliente Unreal Zeus MMO alinhada ao padrao
"cliente solto + servidor valida input/velocidade" (ADR 0038):

- Source/ZMMO/Game/Entity/ — IZMMOEntityInterface, AZMMOEntity (base
  AActor para Mob/NPC/Object), AZMMOPlayerCharacter (player local com
  CMC livre, Enhanced Input, envio de C_INPUT_AXIS), AZMMOPlayerProxy
  (snapshot-only para players remotos).
- Source/ZMMO/Game/Controller/ — AZMMOPlayerController com IMC defaults
  (IMC_Default + IMC_MouseLook) e suporte opcional a virtual joystick.
- Source/ZMMO/Game/Modes/ — AZMMOGameMode (defaults para PlayerCharacter
  / PlayerController), UZMMOGameInstance (auto-connect ao servidor Zeus
  em Init e logging dos eventos OnConnected/OnDisconnected/...).
- Source/ZMMO/Game/Network/ — UZMMOWorldSubsystem (registry
  EntityId -> AActor*, dispatch dos delegates OnPlayerSpawned/Despawned/
  StateUpdate; ignora snapshots locais do cliente solto).
- Config/DefaultEngine.ini — GlobalDefaultGameMode aponta para
  /Script/ZMMO.ZMMOGameMode; GameInstanceClass para
  /Script/ZMMO.ZMMOGameInstance; redirects para a nova hierarquia.
- ZMMO.Build.cs — depende de ZeusNetwork; PublicIncludePaths para a
  nova arvore Game/Entity|Controller|Modes|Network.
- Content — assets do template ThirdPerson (Mannequins, IAs/IMCs,
  Lvl_ThirdPerson + TestWorld). Os Variant_* levels ficam no commit
  inicial mas serao limpos numa proxima sessao com aprovacao explicita
  (Master Rule para .umap/.uasset).

Notas:
- BP_ThirdPersonCharacter/GameMode/PlayerController ainda apontam para
  a hierarquia antiga e estao a aguardar aprovacao para remocao
  (Master Rule).
- README.md descreve a arquitectura e o smoke test de conexao.
