Did that Phactory: Hosting Projects Here

@avivey to do now:

I've used phorge-devcontainer as well and it works great!

I managed to compile xhpast on windows using llvm installed via Scoop. I also have Visual Studio C++ 19 installed which may be required (I saw some suspicious output that indicated that some include files were being pulled from that install somehow).

Nice. Maybe a start-extension Arcanist workflow is a bit overkill, but a boilerplate extension would be lovely
