* add support for const pointers in smart pointers

* use c++11 compatible code

* add template parameter in test

* Make the const-removal clearly visible. This simplifies the production code changes significantly.

…r platforms like macOS). (#5728)

* Revert PR #5700 production code change (pybind11/detail/struct_smart_holder.h).

```
git checkout b194891~1 include/pybind11/detail/struct_smart_holder.h
```

* Introduce `get_internals().get_memory_guarded_delete()`

* [skip ci] Only pass around `memory::get_guarded_delete` function pointer.

* [skip ci] Change a variable name for internal consistency. Add 3 x NOTE: PYBIND11_INTERNALS_VERSION needs to be bumped if changes are made to this struct.

* Add comment: get_internals().get_memory_guarded_delete does not need with_internals()

* Traverse all DSOs to find memory::guarded_delete with matching RTTI.

* Add nullptr check to dynamic_cast overload.

Suggested by ChatGPT for these reasons:

* Prevents runtime RTTI lookups on nullptr.

* Helps avoid undefined behavior if users pass in nulls from failed casts or optional paths.

* Ensures consistent return value semantics and no accidental access to vtable.

* Improve smart_holder unique_ptr deleter compatibility checks across DSOs:

* Replace RTTI-based detection of std::default_delete<T> with a constexpr check to avoid RTTI reliance

* Add type_info_equal_across_dso_boundaries() fallback using type_info::name() for RTTI equality across macOS DSOs

* Rename related flags and functions for clarity (e.g., builtin → std_default)

* Improves ABI robustness and clarity of ownership checks in smart_holder

* Trivial renaming for internal consistency: builtin_delete → std_default_delete

* Add get_trampoline_self_life_support to detail::type_info (passes local testing).

* Polish previous commit slightly.

* [skip ci] Store memory::get_guarded_delete in `detail::type_info` instead of `detail::internals` (no searching across DSOs required).

* Revert change suggested by ChatGPT. After double-checking, ChatGPT agrees this isn't needed.

* Minor polishing.

…der` (#5731)

* Add overload to enable `.def(py::init(&rtrn_shcp))`. Also uncomment `.def(py::init(&rtrn_uqcp))` and `.def(py::init(&rtrn_udcp))`, which happen to work already (not sure what change in the past made those work).

* Introduce `construct_from_shared_ptr()` helper for DRY-ness.
