feat(net+chat): #19 TurbineChat (0xF7DE) codec + ChatChannelInfo + SetTurbineChatChannels parser

Browse source 
Full port of holtburger's TurbineChat sidecar wire path:

- TurbineChat.cs: 0xF7DE codec with three payload variants
  (EventSendToRoom S->C, RequestSendToRoomById C->S, Response).
  10-field outer header (size_first/blob_type/dispatch_type/
  target_type/target_id/transport_type/transport_id/cookie/
  size_second + payload).
- UTF-16LE turbine string codec with 1-or-2 byte variable-length
  prefix (high bit on first byte signals 2-byte form). Mirrors
  holtburger's read_turbine_string / write_turbine_string at
  references/holtburger/.../messages/chat/turbine.rs:502-544.
- SetTurbineChatChannels.cs: 0x0295 GameEvent sub-opcode parser
  (10 x u32 channel ids). Wired through GameEventDispatcher in
  WorldSession ctor; routes to GameEventWiring + TurbineChatState.
- ChatChannelInfo.cs (Core): unified record union with Legacy
  (channel id + name) and Turbine (room id + chat type +
  dispatch type + name) variants, plus IsSelfEchoChannel
  predicate (Tells = false, channels = true so optimistic echo
  is suppressed where the server will echo).
- TurbineChatState.cs (Core): Enabled flag + 10 cached room ids
  + NextContextId() cookie counter starting at 1.
- WorldSession adds TurbineChatReceived + TurbineChannelsReceived
  events; SendTurbineChatTo outbound builds RequestSendToRoomById
  + sends through SendGameAction. ProcessDatagram dispatches
  0xF7DE at the top level.
- GameWindow constructs TurbineChatState, subscribes inbound
  EventSendToRoom -> ChatLog.OnChannelBroadcast; extends I.3's
  SendChatCmd handler to route Turbine kinds (General/Trade/Lfg/
  Roleplay/Society/Olthoi) through TurbineChat first, fall back
  to legacy ChatChannel send when state.Enabled == false.

Round-trip golden fixtures from holtburger source verified for
all three payload variants + UTF-16LE strings (short + long
prefix + non-ASCII Cafe + empty) + SetTurbineChatChannels.

26 new tests:
- TurbineChatTests, SetTurbineChatChannelsTests in Core.Net.Tests
- ChatChannelInfoTests, TurbineChatStateTests in Core.Tests

Solution total: 960 green (243 Core.Net + 625 Core + 92 UI).

ACE doesn't run a TurbineChat server, so codec is "ready when
needed" for retail-server-emulating setups. Legacy ChatChannel
fallback continues to work for current ACE-against-acdream play.
