Add <Version>0.3.1</Version> to STPViewer.csproj and read the assembly
version at runtime for the window title, instead of hardcoding it in
XAML. Now bumping <Version> alone updates the title and the
publish-winapp output folder / exe name in one place.

The project has no runtime or compile-time secrets (offline desktop
tool, no DB/API keys), so the secret/ folder held only example launch
scripts that were never used. Remove it and the related .gitignore
rules; trim references in ARCHITECTURE.md and CLAUDE.md.

- Gizmo now renders in a separate transparent Viewport3D overlaid on
the main view, so the manipulator is never occluded inside solid
parts and is always grabbable from any angle
- Overlay camera follows the main camera (position/dir/FOV/near-far)
on every change; raw Viewport3D lets empty-area clicks pass through
so orbit / zoom / measurement still work; IsHitTestVisible bound to
GizmoEnabled. Mouse-up handled on the overlay (handledEventsToo),
with _gizmoBakePending guarding against double-bake
- Window title shows version (STPViewer V0.3.1)
- Remove the two test STEP models from the repo (customer part
numbers) -> moved to For_AI/ (gitignored); add *.stp/*.step to
.gitignore so CAD files never get committed again
- Docs updated (ARCHITECTURE Phase 11, CLAUDE.md, README)

- New "操作器" toggle: select a file in the tree and a 3-axis gizmo
appears at its center -- XYZ arrows (TranslateManipulator) to move
along an axis regardless of view angle, and rotation rings
(RotateManipulator) to rotate any angle about an axis
- Manipulators bind to a proxy ModelVisual3D; the proxy's transform
is mirrored to all target BodyVisuals during drag (GPU-side, temp)
- On release the accumulated transform is baked into B-rep via
TransformRoot (deferred with Dispatcher.BeginInvoke to avoid
reentrancy with the manipulator's own mouse-up handling); the
gizmo re-centers on the new bounds
- Temporary transforms are cleared with Transform3D.Identity, never
null (HelixToolkit GetTransform crashes on null child.Transform)
- Selecting another file retargets the gizmo; removing the target
hides it
- Docs updated (ARCHITECTURE Phase 10, CLAUDE.md, README)
Known limitation: gizmo handles are occluded inside solid parts
(WPF single depth buffer). Next: always-on-top overlay viewport.

Drag mode set BodyVisual.Transform = null when clearing the temporary
offset on release. HelixToolkit Viewport3DHelper.GetTransform adds
child.Transform to a GeneralTransform3DGroup without a null check, so
the next FindHits after any drag threw ArgumentException and crashed.
Clear the temporary transform with Transform3D.Identity instead.
Root cause confirmed by decompiling HelixToolkit.Wpf GetTransform.

- New Drag mode (hand cursor): left-press a part and drag to move
its whole file along the screen plane; release to commit
- During drag only a temporary TranslateTransform3D is applied
(GPU-side, smooth even on 430k-triangle assemblies); on release
the offset is baked into B-rep + meshes + edges via TranslateRoot,
so measurement accuracy is unaffected
- Merged-mesh hit-testing via _mergedMap (browse rendering active
in drag mode); edges suspended while dragging
- Mouse capture keeps drag alive outside the window; lost capture
commits at current position
- Right-button rotate / wheel zoom / Shift+left pan unchanged
- Rename small test model to test.stp; docs updated
(ARCHITECTURE Phase 9, CLAUDE.md conventions, README)
