Fix stream keep-alive handling; bump to v1.0.0

Force-close each /stream/{channel_id} response instead of allowing
keep-alive reuse. Jellyfin's SharedHttpStream tuner client was reusing
a pooled keep-alive connection mid-stream from an earlier request and
reading raw MPEG-TS bytes as an HTTP status line, failing with
'Received an invalid status line'.

Also broaden the disconnect exception handling to ConnectionAbortedError
alongside ConnectionResetError.
