refactor: add override specifier to type_name method in Core/Types.h

Merges all work from andrea-geo branch:
- Geant material management classes
- Serialization enhancements (read-only, NVP/HRP macros)
- Transform/assembly system improvements
- VTK puppet/viewport updates (orthographic toggle, voxel rendering)
- Property grouping, dynamic properties, NotifyPropertiesUpdated
- Object type identification via uLibTypeMacro
- New tests (PropertyGrouping, ReadOnly, vtkQViewport, PuppetParenting)
- Various gcompose UI fixes

Conflict resolved in CMakePresets.json: kept both 'fast' (clang/lld)
and 'mutom' (stub) presets.

+# Serialization and Archives Internals
+
+This document explains the internal design of the `uLib` serialization system, which is built on top of **Boost.Serialization**. It provides custom archive implementations for various formats (XML, Text, Logging) and introduces **Human Readable Pairs (HRP)** for metadata-rich serialization.
+
+---
+
+## Architecture Overview
+
+The `uLib` archive system extends the standard `boost::archive` templates to add domain-specific features. The main components are:
+
+1.  **Custom Interface Layer**: Extends the default Boost archive API with additional operators and utilities.
+2.  **Specialized Archive Implementations**: Specialized classes for XML, Text, and Logging.
+3.  **HRP Support**: First-class support for `hrp` (Human Readable Pair) wrappers, which carry units, ranges, and descriptions.
+4.  **Static Registration System**: Macros and explicit instantiations to handle polymorphic types and compilation isolation.
+
+---
+
+## Custom Interface Layer
+
+All `uLib` archives use a custom interface defined in `Archives.h` via `uLib_interface_iarchive` and `uLib_interface_oarchive`. These templates add several key features:
+
+| Feature | Operator/Method | Description |
+|---|---|---|
+| **Mapping Operator** | `operator==` | Aliased to `operator&` (Boost's standard mapping operator). |
+| **Trace Operator** | `operator!=` | Used for trace/debug output of strings during serialization. |
+| **Type Registration** | `register_type<T>()` | Registers a class type with the archive's internal serializer map. |
+| **Standard IO** | `operator<<` / `operator>>` | Standard redirect for saving and loading. |
+
+These interfaces are applied to the archives using template specialization of `boost::archive::detail::interface_iarchive` and `interface_oarchive`.
+
+---
+
+## Archive Variants
+
+### XML Archives (`xml_iarchive`, `xml_oarchive`)
+These inherit from `boost::archive::xml_iarchive_impl` and `xml_oarchive_impl`. 
+- **Internals**: They override `load_override` and `save_override` to handle `boost::serialization::hrp<T>` specifically. 
+- **XML Mapping**: When saving an `hrp`, it uses `save_start(name)` and `save_end(name)` to wrap the value in a named XML tag.
+
+### Text Archives (`text_iarchive`, `text_oarchive`)
+Standard text-based archives used for compact serialization. They use `StringReader` to consume decorative text markers during loading.
+
+### Human Readable Text (`hrt_iarchive`, `hrt_oarchive`)
+These are "naked" text archives that suppress most of Boost's internal metadata (object IDs, class IDs, versions).
+- **Goal**: Produce text output that is easy for humans to read and edit.
+- **Internals**: All overrides for Boost internal types (like `object_id_type`, `version_type`, etc.) are implemented as no-ops.
+
+### Log Archive (`log_archive`)
+An XML-based output archive specifically for debug logging.
+- **Internals**: It forces every object into a Name-Value Pair (NVP) even if not provided by the user, and strips all technical metadata to keep the logs clean.
+
+---
+
+## HRP (Human Readable Pair) Integration
+
+`hrp` is a core `uLib` wrapper (defined in `Serializable.h`) that extends Boost's `nvp`:
+
+```cpp
+// Example of HRP usage
+ar & HRP2("Energy", m_energy, "MeV").range(0, 100);
+```
+
+### Internal Handling in Archives
+Archives in `Archives.h` provide specific `save_override`/`load_override` for `hrp<T>`:
+- **XML**: Maps the `name()` to an XML tag.
+- **HRT**: Formats as `name: value [units]\n`.
+- **Log**: Converts it to a standard Boost `nvp` for consistent XML logging.
+
+---
+
+## Registration and Polymorphism
+
+### Registration Macro
+The `ULIB_SERIALIZATION_REGISTER_ARCHIVE(Archive)` macro is crucial for polymorphic serialization. It instantiates the necessary template machinery to link the custom `Archive` type with any `Serializable` class exported via `BOOST_CLASS_EXPORT`.
+
+### Explicit Instantiation
+To reduce compilation times and provide a single point of failure for link-time issues, `uLib` uses explicit instantiations in `src/Core/Archives.cpp`. This file includes the `.ipp` implementation files from Boost and instantiates the `archive_serializer_map` and implementation classes for all `uLib` archive types.
+
+---
+
+## Utility: StringReader
+The `StringReader` utility is used internally by text-based archives to parse and skip literals. For example:
+- When loading a string literal from a text archive, `StringReader` consumes whitespace and ensures the stream matches the expected string, failing if there is a mismatch.
+- This is vital for maintaining the structure of human-readable formats.

+# Geant integration
+
+Geant4 integration in uLib is done through the `HEP/Geant` module.
+The module represets a set of wrapper for geant objects that are also deriving from uLib::Object so they can be used in the uLib::Object tree and visualized with the uLib::Vtk module and driven py properties.
+
+# Geant Solid integration
+
+Geant solid in uLib is represented by the `uLib::Geant::Solid` class and mainly BoxSolid and TessellatedSolid. The solids in Geant does not have the possibility to set properties on the fly so we need to create a new solid every time we want to change the properties of a solid. This is done by creating a new `uLib::Geant::Solid` object and setting the properties of the new solid. The new solid is then added to the `uLib::Geant::Solid` object as a child. The old solid is then removed from the `uLib::Geant::Solid` object as a child. The old solid is then deleted. However id some of the properties can be set then the library will drive the change in the solid update.
+
+The idea is to have a mapping of solid properties that can be used in uLib for Qt representation or vtk representation. then when the property is changed the signaling will update the property in uLib and then the solid will be updated. If the Geant property can be applied to the G4 object underneath then the update will apply the change, in case it is not possible to apply the change to the G4 object underneath then the G4 element will be recreated. 
+In any case a updated singal is emitted and the related element that use that solid is updated ( for instance the scene ).

+
+## ACTIVATE PROPERTIES
+
+ULIB_ACTIVATE_PROPERTIES must run after all member initialization, with the vtable pointing to the most-derived type. This is why it has to be in each constructor — in C++, virtual dispatch only works correctly after a class's vtable is installed, which happens at the start of each level's constructor body.
+
+### Option 1 — End-of-class macro (no constructor boilerplate)
+Declare a private member activator as the last member of the class. Its constructor runs after all other members, and at that point the vtable is already Derived's:
+
+
+// In Property.h, add alongside ULIB_ACTIVATE_PROPERTIES:
+#define ULIB_DECLARE_PROPERTIES(SelfType) \
+private: \
+    struct _PropActivator { \
+        _PropActivator(SelfType* self) { \
+            uLib::Archive::property_register_archive ar(self); \
+            ar & *self; \
+        } \
+    } _prop_activator{this};
+Usage in ContainerBox.h — place it just before the closing brace:
+
+
+class ContainerBox : public TRS {
+public:
+    // ... all constructors, no more ULIB_ACTIVATE_PROPERTIES(*this)
+
+    ULIB_DECLARE_PROPERTIES(ContainerBox)  // ← replaces all 3 constructor calls
+};
+Tradeoff: Works perfectly for single-level classes. For hierarchies where multiple levels use the macro, RegisterDynamicProperty must deduplicate by name (skip if already registered). Requires one line per class in the class body, but zero lines in constructors.
+
+### Option 2 — Lazy init via virtual InitProperties() in Object
+Modify Object to call a virtual hook on first GetProperties():
+
+
+// In Object.h:
+class Object {
+protected:
+    virtual void InitProperties() {}   // override in derived
+public:
+    const std::vector<PropertyBase*>& GetProperties() const {
+        if (!m_propertiesInitialized) {
+            const_cast<Object*>(this)->m_propertiesInitialized = true;
+            const_cast<Object*>(this)->InitProperties();
+        }
+        return m_properties;
+    }
+};
+Then a CRTP base handles the rest without any macro:
+
+
+template<typename Derived>
+class PropertyObject : public Object {
+protected:
+    void InitProperties() override {
+        uLib::Archive::property_register_archive ar(this);
+        ar & *static_cast<Derived*>(this);
+    }
+};
+Usage — just change the base class:
+
+
+class ContainerBox : public PropertyObject<ContainerBox>, public TRS { ... };
+// Nothing else needed — properties activated on first GetProperties() call
+Tradeoff: Most "automatic" — pure inheritance, no constructor or class-body macros. But requires modifying Object (adding m_propertiesInitialized flag + virtual hook), and lazy init means properties aren't available until first access. Also doesn't work well with multiple inheritance (which TRS likely involves).
+
+Option 3 — CRTP doesn't work from the base constructor
+Just to be explicit: a CRTP base that calls ULIB_ACTIVATE_PROPERTIES in its own constructor won't work, because when PropertyObject<Derived>'s constructor runs, the vtable is PropertyObject<Derived>'s — Derived::serialize() hasn't been installed yet. So ar & *self calls Object::serialize() (a no-op).
+
+Recommendation
+Option 1 is the least invasive and safest. Add deduplication to RegisterDynamicProperty in Object.cpp to guard against re-registration when hierarchies stack activators, then replace every ULIB_ACTIVATE_PROPERTIES(*this) in constructors with a single ULIB_DECLARE_PROPERTIES(ClassName) at the end of the class body.
+
+Option 2 is cleaner to use but requires changing the Object interface and has the lazy-init semantic change — only worth it if you want zero-touch activation across the entire framework.
