The logs (and terminal) tab ✕ dismissed the pane from the layout but
never synced the owning store — so the ⌘K toggle was stale and its open
listener called setPaneCollapsed, a no-op when the pane isn't in the
tree. The tab was gone with no way back short of a layout reset.
Route the tab ✕ through closeCollapsePane (dismiss + store sync) so the
toggle stays truthful, and make bindPaneCollapse's open listener call
revealTreePane (un-dismiss + re-adopt) instead of setPaneCollapsed.
