- Added PropTrajectory class for deterministic ballistic calculations. - Introduced StickmanPropInteraction component to manage prop interactions (pickup, drop, throw). - Implemented grip resolution and attachment logic for props. - Added signals for interaction events (prop_picked_up, prop_dropped, prop_thrown). - Defined specifications for prop interaction lifecycle and event rules. - Ensured compatibility with existing prop systems and added new capabilities for prop pickup.
