What
Attaching means connecting your Claude Code window to a session that is running somewhere else. Before, only that session's background tasks were synced to your window.
Workflow runs are now synced as well:
On attach, they are filled in from the session's snapshot.
While you stay connected, they are kept up to date.
When you disconnect, they are cleared.
Why
An attached session can now show workflow runs that were started from another place, not only its background tasks.
