* Fix data race all_type_info_populate in free-threading mode
Description:
- fixed data race all_type_info_populate in free-threading mode
- added test
For example, we have 2 threads entering `all_type_info`.
Both enter `all_type_info_get_cache`` function and
there is a first one which inserts a tuple (type, empty_vector) to the map
and second is waiting. Inserting thread gets the (iter_to_key, True) and non-inserting thread
after waiting gets (iter_to_key, False).
Inserting thread than will add a weakref and will then call into `all_type_info_populate`.
However, non-inserting thread is not entering `if (ins.second) {` clause and
returns `ins.first->second;`` which is just empty_vector.
Finally, non-inserting thread is failing the check in `allocate_layout`:
```c++
if (n_types == 0) {
pybind11_fail(
"instance allocation failed: new instance has no pybind11-registered base types");
}
```

* Fix buffer protocol implementation
According to the buffer protocol, `ndim` is a _required_ field [1], and
should always be set correctly. Additionally, `shape` should be set if
flags includes `PyBUF_ND` or higher [2]. The current implementation only
set those fields if flags was `PyBUF_STRIDES`.
[1] https://docs.python.org/3/c-api/buffer.html#request-independent-fields
[2] https://docs.python.org/3/c-api/buffer.html#shape-strides-suboffsets
* Apply suggestions from review
* Obey contiguity requests for buffer protocol
If a contiguous buffer is requested, and the underlying buffer isn't,
then that should raise. This matches NumPy behaviour if you do something
like:
```
struct.unpack_from('5d', np.arange(20.0)[::4]) # Raises for contiguity
```
Also, if a buffer is contiguous, then it can masquerade as a
less-complex buffer, either by dropping strides, or even pretending to
be 1D. This matches NumPy behaviour if you do something like:
```
a = np.full((3, 5), 30.0)
struct.unpack_from('15d', a) # --> Produces 1D tuple from 2D buffer.
```

Issue: #5224
The `internals.registered_types_py...` line in pybind11.h triggers a
false-positive bounds checking warning in GCC 12.
This is discussed in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115824.
The workaround implemented is taken from suggestions then refactored to
use the `PYBIND11_WARNING_PUSH` and `PYBIND11_WARNING_POP` MACROS.
* `self.__cpp_transporter__()` proof of concept: Enable passing C++ pointers across extensions even if the `PYBIND11_INTERNALS_VERSION`s do not match.
* Include cleanup (mainly to resolve PyPy build failures).
* Fix clang-tidy errors.
* Resolve `error: extra
* factor out platform_abi_id.h from internals.h (no functional changes)
* factor out internals_version.h from internals.h (no functional changes)
* Update CMakeLists.txt, tests/extra_python_package/test_files.py
* Revert "factor out internals_version.h from internals.h (no functional changes)"
This reverts commit 3ccea8cd43.
* Remove internals_version.h from CMakeLists.txt, tests/extra_python_package/test_files.py
* `.__cpp_transporter__()` implementation: compare `pybind11_platform_abi_id`, `cpp_typeid_name`
* Add PremiumTraveler
* Rename test_cpp_transporter_traveler_type.h -> test_cpp_transporter_traveler_types.h
* Expand tests: `PremiumTraveler`, `get_points()`
* Shuffle order of tests (no real changes).
* Move `__cpp_transporter__` lambda to `py::cpp_transporter()` regular function.
* Use `type_caster_generic::load(self)` instead of `cast<T *>(self)`
* Pass `const std::type_info *` via `py::capsule` (instead of `cpp_typeid_name`).
* Make platform_abi_id.h completely stand-alone.
* rename exo_planet.cpp -> exo_planet_pybind11.cpp
* Add exo_planet_c_api.cpp (incomplete).
* Fix silly oversight (wrong filename in `#include`).
* Resolve clang-tidy errors:
```

* Implement exo_planet_c_api GetLuggage(), GetPoints()
* Move new code from test_cpp_transporter_traveler_bindings.h to pybind11/detail/type_caster_base.h, under the name `class_dunder_cpp_transporter()`
* Fix oversight.
* Unconditionally add `__cpp_transporter__` method to all `py::class_` objects, but do not include that magic method in docstring signatures.
* Back out pybind11/detail/platform_abi_id.h for now. Maximizing reusability can be handled separately, later.
* Small cleanup.
* Restore and add to `test_call_cpp_transporter_*()`
* Ensure https://github.com/pybind/pybind11/issues/3788 does not bite again.
* `class_dunder_cpp_transporter()`: replace `obj.cast<std::string>()` with `std::string(obj)`
* Add (simple) copyright notices in all newly added files.
* Globally replace cpp_transporter with cpp_conduit
* style: pre-commit fixes
* IWYU fixes
* Rename `class_dunder_cpp_conduit()` -> `cpp_conduit_method()`
* Change `pybind11_platform_abi_id`, `pointer_kind` argument types from `str` to `bytes`.
This avoids the unicode decode/encode roundtrips:
* More robust (no decode/encode errors).
* Minor runtime optimization.
* Systematically rename `cap_cpp_type_info` -> `cpp_type_info_capsule` (no functional changes).
* Systematically replace `cpp_type_info_capsule` `name`: `"const std::type_info *"` -> `typeid(std::type_info).name()` (this IS a functional change).
This provides an extra layer of protection against C++ ABI mismatches:
* The first and most important layer is that the `PYBIND11_PLATFORM_ABI_ID`s must match between extensions.
* The second layer is that the `typeid(std::type_info).name()`s must match between extensions.
* Fix sort order accident in tests/CMakeLists.txt
* Apply suggestions from code review

is at odds with the `delete src;` three lines up.
In real-world client code `take_ownership` will not exist (unless the client code is untested and unused). I.e. the `delete` is essentially only useful to avoid leaks in the pybind11 unit tests.
While upgrading to clang-tidy 18, the warning below appeared. Apparently it is produced during LTO, and it appears difficult to suppress. Regardless, the best way to resolve this is to remove the `delete` and to simply make the test objects `static` in the unit test code.
