microscope-memory 1.2.0

//! Planning — céllebontás és hierarchikus tervezés

//!

//! Képes:

//! - Célok lebontása részcélokra (HTN planning)

//! - Akciótervek készítése erőforrás becsléssel

//! - Terv végrehajtás monitorozás és replanning

//! - Kockázat becslés és alternatív tervek

//!

//! Kapcsolódások:

//! - executive.rs → terv végrehajtás

//! - heuristic_decision.rs → döntéshozatal

//! - mental_sandbox.rs → előzetes szimuláció

//! - agus.rs → stressz alapú terv módosítás

//! - pattern_recognition.rs → minta illesztés
