Bump pybind11 from 3.0.2 to 3.0.4

[dependabot]

Bumps pybind11 from 3.0.2 to 3.0.4.

Release notes

Sourced from pybind11's releases.

Version 3.0.4

Bug fixes:

• Fixed test builds with installed Eigen 5 by improving Eigen3 CMake package detection. #6036

• Fixed move semantics of scoped_ostream_redirect to preserve buffered output and avoid crashes when moved redirects restore stream buffers. #6033

• Fixed py::dynamic_attr() traversal on Python 3.13+ to correctly propagate PyObject_VisitManagedDict() results. #6032

• Fixed std::shared_ptr<T> fallback casting to avoid unnecessary copy-constructor instantiation in reference_internal paths. #6028

CI:

• Updated setup-uv to the maintained GitHub Action tag scheme. #6035

• Updated pre-commit hooks. #6029

• Updated GitHub Actions dependencies, including actions-setup-cmake and cibuildwheel. #6027

Version 3.0.3

Bug fixes:

• Fixed TSS key exhaustion in implicitly_convertible() when many implicit conversions are registered across large module sets. #6020

• Fixed heap-buffer-overflow in pythonbuf with undersized buffers by enforcing a minimum buffer size. #6019

• Fixed virtual-inheritance pointer offset crashes when dispatching inherited methods through virtual bases. #6017

• Fixed free(): invalid pointer crashes during interpreter shutdown with py::enum_<> by duplicating late-added def_property_static argument strings. #6015

• Fixed function_record heap-type deallocation to call PyObject_Free() and decref the type. #6010

• Hardened PYBIND11_MODULE_PYINIT and get_internals() against module-initialization crashes. #6018

• Fixed static_pointer_cast build failure with virtual inheritance in holder_caster_foreign_helpers.h. #6014

... (truncated)
