The precursors didn't flee the planet. They build the QEF before starting on the Carar research, in the unlikely event that it escaped the facility and infected the planet's ecosystem. And escape it did, the QEF was activated, thus preventing any ships from approaching or escaping the planet. The Precursors on the planet are either dead, or they went into stasis.
