This release moves KactusColors and LibraryModel into libKactusAPI, so
the executable now links symbols from it. Force the in-tree lib dir ahead
of /usr/lib64 in the link path, otherwise an already installed kactus2
shadows the fresh library and the build fails with undefined references.
Also drop py3.10/py3.11 and the stale 3.12/3.13 ebuilds.
