threadFlow
A Flow of ChatThread updates for this handler. Emits the current thread state and subsequent updates triggered by thread recovered events (triggered by refresh), message events (triggered by messages and its methods), and metadata events.
The flow replays the latest thread state when collected. It is safe to collect from multiple places at once (e.g. a thread list and an open conversation for the same thread) — all collectors observe the same sequence of updates, the same as ChatThreadsHandler.threadsFlow.
As with ChatThreadsHandler.threadsFlow, this handler's updates are tied to the chat session that created it: once the underlying connection is closed, this instance stops updating. Calling ChatThreadsHandler.thread again on a ChatThreadsHandler obtained from that same, now-closed session returns the same stale instance — obtain a handler from a freshly connected Chat (e.g. via ChatInstanceProvider, which rebuilds the session on reconnect) instead.
