Herald added a project: clang.

This introduces a few new concepts:

- tweaks have an Intent (they don't all advertise as refactorings)
- tweaks may produce messages (for ShowMessage notification). Generalized Replacements -> Effect.
- tweaks (and other features) may be hidden (clangd -hidden-features flag). We may choose to promote these one day. I'm not sure they're worth their own feature flags though.

Verified it in vim-clangd (not yet open source), curious if the UI is ok in VSCode.
