Summary

Adds a Twitch Chat widget, offered while a Twitch account is set up, with emotes, emoji, badges and name colours, and batches incoming messages so busy chats stay cheap. Disabling an integration now also withdraws its widget types, layouts, folder views and screensavers and keeps its devices offline, including plugins that reconnect while disabled.

Testing

Release build with warnings as errors and all .NET, runtime, web client and desktop-ui suites pass, except Plugin.Cli A_project_is_actually_built_before_its_output_is_resolved, which fails locally with dotnet build exit 155 in its temporary project. Verified with a scratch plugin in a disposable host and with a live Twitch chat in the desktop UI.

Plugin SDK / API compatibility

• No public, non-obsolete SDK or plugin protocol contract was removed or changed
• Contracts were only extended additively (new members with defaults, new optional fields, new message types)

UI model additions: spans on ui.text, overflow clip-start on ui.stack (component version 2 with a fallback). Behaviour change: while the user has an integration turned off, its registrations are validated but not kept and its devices stay offline, listed under behaviour changes that moved no version.
