refactor: rename Puppet class to Prop3D across the codebase

Geant4's G4EXPATShim creates EXPAT::EXPAT (uppercase) with
IMPORTED_LOCATION set to ${EXPAT_LIBRARY}, which is empty when EXPAT
is found via conda's config-mode package (expat::expat, lowercase).

After find_package(Geant4), patch EXPAT::EXPAT with the real library
path taken from expat::expat IMPORTED_LOCATION_NOCONFIG, falling back
to find_library if needed.

+# Skill: Build uLib with Micromamba
+
+This skill provides instructions for building the uLib project using the micromamba environment.
+
+## Context
+- **Environment**: micromamba `uLib`
+- **Output Directory**: `build`
+- **CPU Usage**: All available cores
+
+## Instructions
+
+1. **Environment Setup**:
+   Ensure micromamba is properly initialized and the `uLib` environment is active.
+   ```bash
+   export MAMBA_EXE="/home/share/micromamba/bin/micromamba"
+   export MAMBA_ROOT_PREFIX="/home/share/micromamba"
+   eval "$(/home/share/micromamba/bin/micromamba shell hook --shell bash)"
+   micromamba activate uLib
+   ```
+
+2. **Full Rebuild (if needed)**:
+   If the `build` directory does not exist or a full reconfiguration is required:
+   ```bash
+   conan profile detect --force
+   conan install . --output-folder=build --build=missing
+   cmake --preset conan-release
+   ```
+
+3. **Incremental Build**:
+   Run the build command from the root directory, pointing to the `build` folder and using all cores.
+   ```bash
+   cmake --build build -j$(nproc)
+   ```
+
+4. **Specific Target Build**:
+   To build a specific target (e.g., gcompose):
+   ```bash
+   cmake --build build --target gcompose -j$(nproc)
+   ```

+Viewport click  →  Viewport::SelectProp3D()  →  QViewport::OnSelectionChanged()
-                →  emit puppetSelected(p)
+                →  emit prop3dSelected(p)
                 →  MainPanel: contextPanel->selectObject(p->GetContent())  [updates tree + PropertiesPanel]
                 →  MainPanel: firstPane->setObject(p)  [updates Display Properties panel]

-                →  MainPanel: viewport->SelectPuppet(puppet)  [visual selection in VTK]

 ### Key Patterns
 - **Two signal systems coexist**: Qt signals (`Q_OBJECT`, `connect(...)`) for GUI; `uLib::Object::connect(...)` for domain signals.
-- **Display properties** flow: `Puppet::serialize_display()` → `display_properties_archive` → `RegisterDisplayProperty()` → `PropertyEditor(displayOnly=true)`. Must call `ULIB_ACTIVATE_DISPLAY_PROPERTIES` in the puppet constructor.
+- **Display properties** flow: `Prop3D::serialize_display()` → `display_properties_archive` → `RegisterDisplayProperty()` → `PropertyEditor(displayOnly=true)`. Must call `ULIB_ACTIVATE_DISPLAY_PROPERTIES` in the prop3d constructor.
-- **Puppet ↔ Object map**: `Viewport::m_ObjectToPuppet` allows lookup by domain object; `vtkObjectsContext::GetPuppet(obj)` does the same.
+- **Prop3D ↔ Object map**: `Viewport::m_ObjectToProp3D` allows lookup by domain object; `vtkObjectsContext::GetProp3D(obj)` does the same.

 # Properties and the vtk-gui representation
 
-This is the rationale behind the connection between TRS properties and Puppet Transformation.
+This is the rationale behind the connection between TRS properties and Prop3D Transformation.
 
 The properties from model get propoagated via Object signalling system (the Update signal) to the vtkRepresentation and to the Qt widgets so that the overall transformation of the model reflects into a modification of its representation in vtk and in the gui. 
 
-In addition the properties need to be adjusted also from vtk, for example if user uses handlerwidget to change the transformation this is eventually applied to Puppet and Puppet should propagate the transformation change to the vtk representation object (for instance vtkContainerBox) and the latter eventually propagates the change into the model.

-the Puppet or the vtk representation wrapper ( vtkContainerBox for instance is the wrapper od ContainerBox ) should not directly show the transformation of the handlerwidget but it should show the transformation of the model once applied so we are always seeing the actual aspect of the model reflected to the vtk representation and not the other way around.

 So in syntesis the model is the master and the vtk representation and the gui are the slaves of any modification, but the vtkHandlerWidget is able to apply a transform that should be applied to the model and then the model should propagate the transformation change to the vtk representation and to the gui.
 
-## The Puppet

-The puppet is the proxy of the spatial placement of objects in the scene. Puppets should have an internal ContainerBox that is shown in the scene around the content to be able to pick Puppet from vtkViewport using the handler widget. The HandlerWidget moves the Puppet ContainerBox (the red Highlight element whe selected) to reflect the handler current transformation, but the transformation is propagated to the derived Puppet classes like vtkContainerBox.
