fix(core): do not auto-exit tui when there are multiple failed tasks (#31631)

## Current Behavior

When the user hasn't interacted with the TUI and has not disabled the
auto-exit functionality, it will always auto-exit regardless of the
number of failed tasks.

## Expected Behavior

When the user hasn't interacted with the TUI and has not disabled the
auto-exit functionality, it should not auto-exit if there are multiple
failed tasks. Additionally, as long as no terminal output panes are open
(e.g., the run one command will always display the initiating task
terminal pane), it should focus and open the first failed task.

If all tasks succeed or there's only one failure, it should continue to
auto-exit.
