- Rename Result to PackResult to avoid confusion with Result<T> - Add PackingRequest as immutable configuration replacing mutable engine state - Add PackingStrategy enum (AdvancedFit, BestFit, Exhaustive) - Implement pipeline pattern for composable packing steps - Rewrite AdvancedFitEngine as stateless using pipeline - Rewrite BestFitEngine as stateless - Add ExhaustiveFitEngine with symmetry breaking for optimal solutions - Tries all bin assignments to find minimum bins - Falls back to AdvancedFit for >20 items - Configurable threshold via constructor - Update IEngine/IEngineFactory interfaces for new pattern - Add strategy parameter to MCP tools Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
