Add predictive targeting and adjust combat flow

Introduce predictive targeting based on entity eye positions and relative velocity (predictDistance) and change entity query to use a Box around the player's eye position and the prediction check. Rework combat item handling: ensure axe-block breaking logic checks axe availability first, perform mace attack before equipping Elytra, and only equip Elytra if present. Add necessary imports and small refactors for readability.
