v0.2.0

What's Changed

three-cad-viewer v4 Integration

• Upgraded to three-cad-viewer v4.1.0 from npm registry (previously pinned to git commit)
• Native addPart() / removePart() API — no more workarounds
• Batched updates with skipBounds + updateBounds() for ~140x faster part operations (50 parts: 7ms vs 1000ms)
• Native visibility state preservation across part updates
• Native camera_distance and reset location updates after updateBounds()

Simplified JS Widget

• Reduced JS from ~1270 lines across 6 files to ~185 lines in a single file
• Deleted cad-group-factory.js, clipping-extension.js, live-viewer.js, part-manager.js, state-manager.js
• Zero workarounds remaining — everything handled natively by TCV

Test Coverage

• Added E2E tests for visibility persistence across slider changes (008, 009)
• Added E2E test for resize object after height change (010)
• Updated all visual regression snapshots for TCV 4.1.0
• 34 unit tests + 10 E2E tests passing

Other
