Remote session connections now report who is allowed to write to the session

When connecting to a remote session, Claude Code now reads whether only the owner's account or only others may write to it, and logs the answer

What

When Claude Code opens a live connection to a remote session, it now reads a new piece of information sent back by the server, the x-ccr-session-writers header. It turns this into one of two answers: only the owner's account may write to the session, or only accounts other than the owner may. Claude Code records that answer when the connection succeeds, and records that the header was missing or unreadable when it cannot get an answer.

Why

This prepares for remote sessions that more than one account can write to. For now the answer is only recorded.
