3.0.12 (2025-02-11)

Bugs fixed

* Release 3.0.11 introduced some incorrect ``noexcept`` warnings.
* Conditional assignments to variables using the walrus operator could crash.
* Dict assignments to struct members with reserved C names could generate \ 
invalid C code.
* Fused ctuples with the same entry types but different sizes could fail to compile.
* In Py3, `pyximport` was not searching `sys.path` when looking for importable \ 
source files.
* Using `& 0` on integers produced with `int.from_bytes()` could read \ 
invalid memory on Python 3.10.
* Modules could fail to compile in PyPy 3.11 due to missing CPython specific \ 
header files.
* Minor fix in C++ ``partial_sum()`` declaration.
