+Terminal PTY size is last-interacting-client-wins. A client claims the PTY size only when its terminal viewport genuinely changes size or the user focuses/taps the terminal. Passive rendering work — attaching, restoring visibility, font settling, renderer refits, or just looking at a visible terminal — must not send a resize frame. The server does not broadcast resize ownership; the resized PTY redraws through normal output, and every attached client renders that output in its own local viewport.

 There is also a separate file-transfer binary frame format in the same directory, used for download/upload streams.
