The new-agent (`n`) flow's tmux branch was leaving keyboard focus in the dashboard pane after compose-up + provision finished and claude landed in the right pane — same situation as Enter re-attach before its `focus_right_pane` fix. The operator just spun an agent up; they want to type at it. Pass `focus_right_pane=True` to `_attach_in_tmux` from the new-agent flow. `tmux select-pane` runs after the respawn.
