Module client 

Blocking unix-socket client for the semantic side-channel.

Dormant rule. Without TERMWRIGHT_ENDPOINT and TERMWRIGHT_TOKEN in the environment Client::from_env returns None: the application opens no socket, writes no marker, and renders exactly the bytes it would have rendered anyway.

The client is deliberately blocking and single-threaded. A TUI renders on one thread and the marker must follow that render’s last byte, so Client::publish does its socket work inline and hands back the marker to write. Driver requests are picked up by Client::poll, which never blocks.

Structs
