    PlanSys2 moves to Kairos and STN 🚀

    PlanSys2 is transitioning to Kairos, a new temporal and numeric PDDL planner, and STNBTBuilder, a new plan BT Builder for the executor. Kairos supports PDDL3 and outperforms existing planners on various benchmarks. STNBTBuilder enables more parallel execution by respecting temporal constraints between actions.
