perf: Background parallel section clip, parallel transform bake, faster gap refine (v0.4.0)
- ApplySection: snapshot on UI thread, clip whole scene with Task.Run + Parallel.For, swap once; _sectionApplying/_sectionReapply guard reruns with latest params when settings change mid-clip - TransformRoot: per-face parallel mesh transform (frozen in/out); B-rep Modify and visual-tree assignment stay sequential - InterferenceService.ApproxMinDistance: AABB squared-distance early reject + Parallel.For refine with thread-local best - Stability: global exception handlers in App.xaml.cs (dispatcher/task/ appdomain -> %LOCALAPPDATA%/STPViewer/error.log); IsBusy CanExecute guards on Import/Rotate/Interference; whole-batch busy + reentrancy guard in ImportFilesAsync - Refactor: split MainViewModel into partial classes (Drag/Gizmo/ Section/Interference/Export); dedupe merged-mesh build and ClosestPointOnTriangle - Bump version to 0.4.0 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
