Dear Maintainer,

We would like to remove llvm-toolchain-19 from the archive.
Please update to 21.

Thanks
Sylvestre

Hello,

just changing the build dependency is *not* enough.
The code itself must be updated to be compatible with llvm/clang 21.

Luckily upstream already did this in 0.25:
<https://github.com/include-what-you-use/include-what-you-use/releases/tag/0.25>
<https://github.com/include-what-you-use/include-what-you-use/releases/tag/0.26>
