* 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.
* Revert PR #5700 production code change (pybind11/detail/struct_smart_holder.h).
```
git checkout b19489145b2c7a117138632d624809dfb3b380bb~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.
* 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.

* Refactor internals to use a holder that manages the PP
* Fix cleanup/destruction issues.
* Fix one more destruction issue
Should now just be able to delete the internals PP on destruction
* Make clang-tidy happy
* Try to fix exception translators issue on certain platforms
Also fix a couple more pedantic warings
* Fix test, after internals is free'd it can come back at the same address
So instead, just make sure it was zero'd and don't try to compare the addresses.
Also a little code cleanup
* Comment tweak [skip ci]
* Switch to ifdef instead of if
* Re-enable subinterpreters in iOS
* style: pre-commit fixes

* First draft a subinterpreter embedding API
* Move subinterpreter tests to their own file
* Migrate subinterpreter tests to use the new embedded class.
* Add a test for moving subinterpreters across threads for destruction
And find a better way to make that work.
* Code organization
* Add a test which shows demostrates how gil_scoped interacts with sub-interpreters
* Add documentation for embeded sub-interpreters
* Some additional docs work
* Add some convenience accessors
* Add some docs cross references
* Sync some things that were split out into #5665
* Update subinterpreter docs example to not use the CPython api
* Fix pip test
* style: pre-commit fixes
* Fix MSVC warnings
I am surprised other compilers allowed this code with a deleted move ctor.
* Add some sub-headings to the docs
* Oops, make_unique is C++14 so remove it from the tests.
* I think this fixes the EndInterpreter issues on all versions.
It just has to be ifdef'd because it is slightly broken on 3.12, working well on 3.13, and kind of crashy on 3.14beta. These two verion ifdefs solve all the issues.
* Add a note about exceptions.
They contain Python object references and acquire the GIL, that means they are a danger with subinterpreters!
* style: pre-commit fixes
* Add try/catch to docs examples to match the tips
* Python 3.12 is very picky about this first PyThreadState
Try special casing the destruction on the same thread.
* style: pre-commit fixes
* Missed a rename in a ifdef block
* I think this test is causing problems in 3.12, so try ifdefing it to see if the problems go away.
* style: pre-commit fixes
* Document the 3.12 constraints with a warning
* Apply suggestions from code review
