feat(chat): Phase H.1 Talk/Tell/ChatChannel + HearSpeech + ChatLog
Completes the chat-wire layer end-to-end: outbound Talk (/say), Tell
(/tell), ChatChannel, + inbound HearSpeech (0x02BB) / HearRangedSpeech
(0x02BC) routed into a unified ChatLog that also consumes the already-
parsed GameEvent ChannelBroadcast / Tell / TransientMessage / Popup.
Wire layer (AcDream.Core.Net/Messages):
- ChatRequests.BuildTalk (0x0015, inside 0xF7B1): gameActionSequence
+ string16L message. PackString16L helper with 4-byte pad.
- ChatRequests.BuildTell (0x005D): targetName + message, each
string16L with its own padding.
- ChatRequests.BuildChatChannel (0x0147): channelId + message.
- HearSpeech.TryParse handles BOTH 0x02BB local AND 0x02BC ranged —
single parser with IsRanged flag in the returned record. Standalone
GameMessage (NOT wrapped in 0xF7B0).
WorldSession integration:
- ProcessDatagram branch for HearSpeech.LocalOpcode /
HearSpeech.RangedOpcode; fires new SpeechHeard event.
- Places the new branch before the 0xF7B0 GameEvent branch so ordering
stays stable.
Core layer (AcDream.Core/Chat):
- ChatEntry record: (Kind, Sender, Text, SenderGuid, ChannelId, Received).
- ChatKind enum: LocalSpeech, RangedSpeech, Channel, Tell, System, Popup.
- ChatLog: ring-buffer (default 500) of entries; adapters for every
inbound source (OnLocalSpeech, OnChannelBroadcast, OnTellReceived,
OnSystemMessage, OnPopup) plus OnSelfSent for echoing outbound.
Fires EntryAppended so UI panel can scroll / highlight.
Tests (15 new):
- ChatRequests: Talk / Tell / ChatChannel byte-exact encoding (including
string16L padding edge cases).
- HearSpeech: local + ranged round-trip, wrong-opcode returns null.
- ChatLog: local / ranged / channel / tell / system / self echo,
ring-buffer drops oldest, Clear empties.
Build green, 570 tests pass (up from 555).
With the chat wire layer in place, Phase H.1's "chat window panel"
(UI slice 05) is purely a UI task: instantiate ChatLog, bind to
EntryAppended, feed rows into the retail-UI widget toolkit. No more
protocol gaps.
