claude -n should display session name on prompt bar like /rename does

Summary

When starting a session with claude -n session-name, the session name is set for identification/resume purposes but is not displayed on the prompt bar border. Using /rename session-name inside the session does display it on the prompt bar.

This is inconsistent — both set the session name, but only /rename shows it visually.

Expected behavior

claude -n session-name should display the session name on the prompt bar border, just like /rename does.

Current behavior

• claude -n brain → session named "brain" but prompt bar shows no label
• /rename brain inside session → session named "brain" and prompt bar shows the label

Workaround

Run /rename <name> after starting the session, which is redundant since the name was already set via -n.
