Session names can contain pipes but never colons, so split fields on
colons instead. Remember refreshes that arrive while the indicator is
already polling, and jump to the most recently used tmux client rather
than an arbitrary one.

Show a bar indicator whenever tmux has flagged a window, the same state
that highlights the tab, and jump to it on click or with Super + Ctrl + J.
Tmux hooks push the state to the shell, so nothing polls while no pane is
waiting.
