Stream the inbox's change events
Server-sent event stream of inbox changes. One coalesced event kind — inbox_invalidated — tells the client to refetch what it shows; hello on connect means the same thing. The server closes the stream after a few minutes with a reconnect frame. Requires Clerk authentication; API keys are rejected.
Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Response
A stream of change events; each frame's data is one event.
The single inbox change-feed event: something changed, refetch what you show.
thread_id narrows the hint to one thread; None means the thread list
itself changed. The frontend debounces and invalidates either way, so one
coalesced event kind is all the wire ever carries.
