Add .clangd file

[noahfrn]

I've added a default .clangd compilation database for people who might be using clangd directly as their LSP, for example from vim/neovim. The default dev profile will export the compile commands by default, so I think it makes sense to point the default CompilationDatabase to that directory as well.

That seems like a good idea, however the file seems to only work for a single build directory: https://clangd.llvm.org/config#compilationdatabase

The user presets by default already come with many possible build folder locations: https://github.com/friendlyanon/cmake-init/blob/master/cmake-init/templates/common/CMakeUserPresets.json#L17

What I think would work is if this file was also in .gitignore, since then multiple users won't clobber each others' setup.

Please move this file to cmake-init/templates/common and add it to the .gitignore file as well.

If this can just say build/dev then please make it so.

Hey @friendlyanon, have been busy sorry ! Not sure what you mean exactly by adding it .gitignore, apologies, I'm not familiar with the internals of cmake-init ! The file is already currently included in the .gitignore under cmake-init/templates/common.

I haven't noticed! Then please do the other requested changes.
