Bump pybind11 from 2.12.0 to 3.0.2

[dependabot]

Bumps pybind11 from 2.12.0 to 3.0.2.

Release notes

Sourced from pybind11's releases.

Version 3.0.2

New Features:

• Added helper functions to py::array that return shape and strides as std::span when available. #5974

Bug fixes:

• Added fallback locking for Python 3.13t where PyCriticalSection_BeginMutex is unavailable. #5981

• Fixed race condition in py::make_key_iterator with free-threaded Python. #5971

• MSVC 19.16 and earlier were blocked from using std::launder due to internal compiler errors. #5968

• Internals destructors were updated to check the owning interpreter before clearing Python objects. #5965

• Internals shutdown handling was refined in two iterations before release: an initial finalization-time cleanup was followed by a safety adjustment to avoid late-shutdown py::cast segfaults. #5958 #5972

• Fixed ambiguous str(handle) construction for object-derived types like kwargs or dict by templatizing the constructor with SFINAE. #5949

• Fixed concurrency consistency for internals_pp_manager under multiple-interpreters. #5947

• Fixed MSVC LNK2001 in C++20 builds when /GL (whole program optimization) is enabled. #5939

• Added per-interpreter storage for gil_safe_call_once_and_store to make it safe under multi-interpreters. #5933

• A workaround for a GCC -Warray-bounds false positive in argument_vector was added. #5908

• Corrected a mistake where support for __index__ was added, but the type hints did not reflect acceptance of SupportsIndex objects. Also fixed a long-standing bug: the complex-caster did not accept __index__ in convert mode. #5891

• Fixed *args/**kwargs return types. Added type hinting to py::make_tuple. #5881

• Fixed compiler error in type_caster_generic when casting a T implicitly convertible from T*. #5873

• Updated py::native_enum bindings to unregister enum types on destruction, preventing a use-after-free when returning a destroyed enum instance. #5871

... (truncated)
