feat(statusbar): hide the per-turn session readouts by default

The running/session timers and the context meter light up whenever a
session works, so the bar filled with diagnostics most users don't watch
every turn. They join the same right-click show/hide menu the route
shortcuts and terminal toggle already use: hidden out of the box, opt in
via a toggleLabel, choice persisted per install.
