building pydantic-core with modified jiter

[FCare]

Chaquopy 16.0.0

chaquopy {
defaultConfig {
version = "3.12"
pip {
install("pydantic-core==2.18.4")
install ("pydantic")
install("websocket-client==1.8.0")
install("langgraph==0.1.19")
}
}
}

Hi, I would like to be able to use langgraph with chaquopy. As a lot of people here, I have the "pedentic v2" issue due to langgraph dependency. And the pydantic<2 workaround can not work.

Based on cryptography example, I tried to compile pydantic-core locally with build_wheel, by adding a package. This was failing due to jiter compliation issue.

Then I went to jiter 0.8.0 compilation. Jiter is using python and it had an issue with pyo3::ffi. Which I fixed by simply removing an optimization. I finally get a chaquopy/server/pypi/dist/jiter/jiter-0.8.0-0-cp311-cp311-android_24_x86_64.whl file.

But I can not apply my patches to the pydantic-core because is still resolve dependencies using cargo registry (cargo/registry/src/index.crates.io-6f17d22bba15001f/jiter-0.8.2/src/py_string_cache.rs).

Is there a way to force my package pydantic-core to use the jiter whl file?

Thanks a lot for your help and your work :-)
