Gateway tests build adapters via object.__new__() without __init__ (the documented bare-instance pattern), so the new _status_text dict must be accessed through getattr guards in set_status_text, the _keep_typing finally cleanup, and the Slack send_typing read — same treatment as other post-hoc __init__ attributes. Fixes CI shard 2/8 (test_active_session_text_merge).
