All 27 PyTypeObject declarations in namespace mcrfpydef headers changed
from `static` to `inline` (C++17), ensuring a single global instance
across translation units. This fixes the root cause of stale-type-pointer
segfaults where only the McRFPy_API.cpp copy was PyType_Ready'd.
Replaced ~20 PyTypeCache call sites and 2 PyRAII::PyTypeRef lookups with
direct &mcrfpydef::Type references. Deleted PyTypeCache.h/.cpp,
PyObjectUtils.h, and PyRAII.h (all were workarounds for the static bug).
228/228 tests pass.

EntityCollection3D now has API parity with UIEntityCollection:
- pop(index=-1): Remove and return entity at index
- find(name): Search by entity name, return Entity3D or None
- extend(iterable): Append multiple Entity3D objects
Also adds `name` property to Entity3D for use with find().

screen_to_world() previously only intersected the Y=0 plane.
Now accepts an optional y_plane parameter (default 0.0) for
intersecting arbitrary horizontal planes.

The root cause was PyViewport3DType being declared `static` in
Viewport3D.h, creating per-translation-unit copies. Entity3D.cpp's
copy was never passed through PyType_Ready, causing segfaults when
tp_alloc was called.
Changed `static` to `inline` (matching PyEntity3DType and
PyModel3DType patterns), and implemented get_viewport using the
standard type->tp_alloc pattern.
