feat: Initial release v0.1.0

STP/STEP 3D viewer (WPF, .NET 8) - CADability + HelixToolkit.Wpf: - Multi-file import (STEP/STL/DXF) with STEP assembly tree (per-node visibility/color cascade, zoom-to) - Measurements: point / distance / edge / face / circle / angle / face-to-face distance (B-rep exact where available) - Assembly verification: two-point align (translate), 3-point align (rotate+translate via RigidAlign), axis rotate 90, interference check (tri-tri intersection + min gap) - Section view (CPU mesh clipping, originals preserved) - mm/inch toggle, CSV export (UTF-8 BOM), 2x PNG screenshot - Performance: per-file merged edge lines, per-leaf merged mesh in browse mode, no BackMaterial on closed solids, edge suspend during camera interaction, parallel leaf triangulation with retry - SmokeTest CLI: import pipeline, --tree, --clip-test, --interference-test, --align-test (all passing) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
