v4.1 收尾: - IncrementalUpdateEngine: dirty flag propagation, cache invalidation - LargeAssembly: InstanceCache, assembly instancing - STEP import: robust/graceful parsing with skip tracking v4.3 分析工具: - Mass properties (volume, centroid, inertia tensor) - Clearance analysis, wall thickness analysis - Enhanced drawing: hidden-line removal, offset sections, BOM - DXF import (LINE/CIRCLE/ARC/LWPOLYLINE/SPLINE → B-Rep extrusion) v4.4 地基加固: - ToleranceChain: RSS cumulative tolerance propagation (7 tests) - Euler operations: MEV/KEV/MEF/KEF/KEMR/MEKR (20 tests) - Replace hardcoded tolerances with ToleranceConfig in validate - Fix incremental_update test API mismatch (15/15 pass on Linux) Docs: - v4.1-v4.4 development plans + roadmap updated - v4.4 marked complete on Linux 30 files, +3424/-210
