claude attach and claude logs accept a session name

What

A background session is a Claude Code session that keeps running without a terminal window attached. claude attach reconnects you to one, and claude logs shows its output. Both used to need the session's id. They now accept <id|name>:

• claude attach <id|name>: the help text adds that part of the session name works too.
• claude logs <id|name>: finds a session by its name or part of it. If several sessions match, it lists them, including the text of finished sessions. Before, it only matched the start of an id.
• Both share the same lookup, whose help text says: "Part of the session name works in place of the id. Put a name with spaces in quotes."

Why

You can reach a background session by the name you gave it instead of looking up its id. If a name has spaces, put it in quotes. If a partial name matches more than one session, claude logs shows the matches so you can pick.
