[Bug] Status line truncated when attached to claude agents managed session

Bug Description
When attaching to a managed session from claude agents, the status line (custom) in the input area is truncated — it cuts off mid-line instead of displaying fully, unlike in a standalone session where it renders completely.

Also just want to say — claude agents is a fantastic feature, really appreciate the work that went into it! <3
