Shellcove Mac 1.2.6

Added — richer window text styling

• Window Text maps factual Mac Accessibility structure such as role, focus, and selection into existing style runs without changing the wire protocol.

Changed — protocol compatibility

• Mac and iOS validate protocol compatibility by app major/minor line, so 1.2.x builds remain compatible while mismatched lines fail explicitly.

Changed — weak-network remote desktop

• Remote Desktop lowers frame rate and bitrate before reducing clarity, including a low-refresh fallback instead of freezing.
