Patch release on 2025.12.0, extending submodule build support

This is a patch release fleshing out more options (mostly in our CMake support) for building pybind11 submodules using PYB11Generator.

v2025.12.0

Adding better support for pybind11 v3 features (plus some general updates).

• Update generated enum bindings to use native_enum
• Better support for new holder types, and how to overide them.
• Updated default holder type to py::smart_holder
• Adding support for creating pybind11 submodules
• CMake and documentation updates

v2025.01.0

This release includes a few feature improvements and updates our pybind11 version.

• PYB11Generator can now optionally generate multiple pybind11 C++ output files for a module to allow parallel compilation
• The provided CMake rule has been updated to account for this new MULTIPLE_FILES option, which is OFF by default.
• For developers there is a new feature that allows PYB11Generator to skip regenerating some C++ files if they are specially annotated. This is a dangerous feature and should only be used by developers trying very specialized changes to the generated pybind11 code.
• The version of pybind11 PYB11Generator is bundled with has been updated to 3.01.

v2.1.0

Minor feature release for PYB11Generator.

• We have added better support for operators, with the option of explicitly providing the implementation (via @PYB11implementation) for operators such as __mul__, __add__, etc.
• In such cases there is also a new decorator (@PYB11operator) that should also be added to to such operator overloads.
• Updated the operator list to reflect Python 3 semantics, particularly with the addition of __truediv__ and __floordiv__ rather than the old __div__ operation.

v2.0.3

Patch release for PYB11Generator. Mostly changes to CMake build rules since the last tag/release.
