fix: focus the next session or show the splash when one closes#30
Merged
Conversation
When the focused session ended and nothing was free to attach, the ui destroyed the dead view and parked on a 'no session focused' placard, which was permanent when the only sessions left were held by other clients or hosted this ui. Now the refresh falls back to selecting (without attaching) the most recently active session, the same fallback startup uses, so a held session gets the 'attached elsewhere' hint instead. When nothing is selectable at all, the viewport shows the splash, and the placard branch is gone.

Summary
Closing a session in
boo uicould leave the viewport on a permanentno session focused pick a session on the leftplacard, even when there was nothing pickable. The session refresh already auto-attaches the most recently active free session when the focused one dies; the placard appeared whenever no free candidate existed, most commonly when runningboo uiinside a boo session (the host is never an automatic candidate) and killing the last other session.Changes:
attached elsewhere click the session to take it overhint instead of the placard.no session focusedbranch is deleted; focus moves to the next session automatically as before when one is free.Automatic focus still never steals: switching to a held session would yank it from another terminal, so it is selected and explained, not attached.
