I installed it using my GNU/Linux distribution's package manager.
That's Gentoo.

I've got tree-sitter-cpp 0.20.0. In /usr/lib64, I get:
/usr/lib64/libtree-sitter-cpp.so -> libtree-sitter-cpp.so.13

Yes, it's complete. I just tried following my own recipe exactly, and
it produced the unwanted results described.
The feeling at the moment is that that libtree-sitter-cpp.so.13 isn't
compatible with Emacs 29.
