feat(v4.4): complete remaining v4.1-v4.4 features + precision tolerance + Euler ops
...
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
