Replaces NullCommandBus.Instance in PanelContext with a real
LiveCommandBus when a live session is active. Panels publish
SendChatCmd; the host routes it to the right wire opcode + emits
a ChatLog.OnSelfSent local echo (optimistic; retail-equivalent
for Talk).
Pieces:
- ChatChannelKind enum (UI.Abstractions) - mirrors holtburger's
ChatChannelKind (references/holtburger/.../client/types.rs:35-49).
- SendChatCmd record (UI.Abstractions) - (Channel, TargetName?, Text).
- LiveCommandBus (UI.Abstractions) - single-handler-per-type;
Register<T> throws on double-register; Publish<T> logs missing
handler but does not throw.
- ChannelResolver (UI.Abstractions) - port of holtburger's
resolve_legacy_channel (client/commands.rs:50-62) mapping
ChatChannelKind to legacy ChatChannel ids verbatim from
holtburger-protocol/.../chat/types.rs:8-24 (Fellow=0x0800,
AllegianceBroadcast=0x02000000, Vassals=0x1000, Patron=0x2000,
Monarch=0x4000, CoVassals=0x01000000).
- WorldSession.SendTalk / SendTell / SendChannel - 3-line wrappers
around existing ChatRequests.Build* + SendGameAction. Internal
GameActionCapture seam + InternalsVisibleTo for tests.
- GameWindow registers SendChatCmd handler: Say -> SendTalk +
ChatLog echo, Tell -> SendTell + echo, channel kinds ->
ChannelResolver.Resolve -> SendChannel + echo.
12 new tests across SendChatCmd + LiveCommandBus + ChannelResolver
+ WorldSessionChat. NullCommandBus.Instance retained for back-compat
when no live session.
Solution total: 893 green (51 + 229 + 613).
