Under the hood
The title bar's agent name and tmux hint are now computed as two separate, independent pieces
What
The internal function that decides what to show in the title area (either your own agent's name, or a hint like "View teammates: tmux ...") now returns two separate pieces, an agent value and a tmuxHint value, instead of a single combined text-and-color value. It also now takes its inputs (session state, team context, and whether it's running inside tmux) as explicit parameters instead of reading them internally.
Why
This is an internal restructuring of how the title bar's contents are computed; the finding does not describe any visible change to what appears in the title bar.
