chore(eventsub): add operator== and indicator for shared chat

[Nerixyz]

To not confuse moderators, we should ignore moderation events when using shared chat (I believe that's what we're implicitly doing in PubSub as well).

[iProdigy]

i don't think we do this in pubsub, but maybe we could add this suffix to the moderation messages: for the duration of the shared chat session

e.g., sharedMod banned badGuy for the duration of the shared chat session

After claryfing with @iProdigy - moderation actions that happen in the other room during a shared chat session do take effect in your chat, so I think it would make sense to show them still, but maybe with an extra piece of text attached to it like they mentioned above

moderation actions that happen in the other room during a shared chat session do take effect in your chat,

There's little to no documentation on this well-thought-out feature. Do emoteonly and friends apply as well? Also, what's the purpose of having shared_chat_* then?

[iProdigy]

yeah i agree it's not adequately explained in the dev docs

the user facing docs do explain it with a complicated table https://link.twitch.tv/SharedChatMod

also ive written my own explainer at https://twitch4j.github.io/chat/shared-chat/

back to your question: roomstate does not apply to other channels, neither do automod settings or blocked/permitted terms

[github-actions]

clang-tidy made some suggestions

[iProdigy]

sorry if i wasn't clear earlier: we only have to annotate (un)ban/(un)timeout - warn/(un)mod/(un)timeout/(un)raid/etc are not mirrored (and shared_chat_delete is a legit deletion, so no suffix needed for that either)

[Nerixyz]

warn/(un)mod/(un)timeout/(un)raid/etc are not mirrored

... so this is a mistake in the docs? The warn example here shows different users in broadcaster vs source.

[iProdigy]

yeah believe that's a docs error (for eventsub; in pubsub it is mirrored)

[Nerixyz]

Thank you for clarifying. tl;dr: anything, but the shared_* events aren't mirrored.

operator== is still a useful feature, same as isSharedChat (maybe we need that for the shared-chat events).
