Subject: [PATCH] fix(website): prevent duplicate startTracking causing
 rudderQueue error

Guard startTracking with a module-level initialized flag so route changes
and React strict-mode double-effects do not append a second rudderstack
script, whose onload would iterate an already-drained (undefined) queue.
