v0.2.7

Refactoring

• Extracted ChatMessageManager from MainWindow — message storage, formatting, and mutation logic now in a dedicated class, reducing MainWindow complexity
• Split ChatRenderer.cs (8 classes, 548 lines) into 7 individual files: ChatSegment, ChatLine, ChatListSource, ChannelListSource, UserListSource, ChatColors, ColorHelper, RenderHelpers
• Extracted ConnectionManager from AppOrchestrator — connection lifecycle, authentication, SignalR event wiring, and channel tracking now in a dedicated service
• Extracted AvatarHelper — deduplicated avatar upload logic previously duplicated in /avatar command and profile edit dialog
• Consolidated ProfileEditDialog.ParseHexToTrueColor into shared ColorHelper.ParseHexToColor
• Extracted UserSession — session state (Username, Status, StatusMessage) now in a dedicated class instead of scattered fields
• Replaced 21 inline command handler lambdas with named HandleCmd* methods for improved readability
• Extracted shared CleanupConnectionAsync to deduplicate disconnect/logout cleanup logic
• Reorganized flat UI/ folder (19 files) into subfolders: Chat/, Dialogs/, ListSources/, Helpers/ with matching namespaces
• Moved AsyncRunner from project root to Services/ with updated namespace
• Renamed ColorHelper → HexColorHelper to avoid namespace collision with Terminal.Gui's ColorHelper NuGet dependency
• Moved hue_icon.ico to Client/Assets/, removed duplicate from Server (Server now references shared icon via relative path)

Bug Fixes

• Fix user list empty on initial connect — FetchAndUpdateOnlineUsers was called before InvokeUI set the current channel, causing an early return

Infrastructure

• Switch Terminal.Gui from local fork submodule back to NuGet package (2.0.0-develop.5039) — transparent color PR merged upstream
• Remove Terminal.Gui submodule, .gitmodules, and root nuget.config workaround
• Remove rm -f submodule nuget.config steps and submodules: recursive from all 3 CI workflows (ci, docs, release)
• Remove --exclude src/Terminal.Gui/ from format check
