Root page loads should not automatically project a localStorage-saved running session into the active pane. Keep explicit /session/<sid> behavior unchanged while leaving the saved session discoverable from the sidebar.
(cherry picked from commit bb60cf21d911a84e285363bcecf46fb441181fb9)
Adds a 'storage' event listener for the hermes-webui-session localStorage key. Idle tabs auto-load the new active session and re-render the sidebar; busy tabs show a toast and do not interrupt the active turn.
