ZSTD is dual license BSD and GPL-2. So AGPL-3 is fine, as would be GPL-2
or GPL-3.

Ok.

I would use Yann Collet as author/contributor and Facebook only as
copyright holder.

What is the content of the LICENSE file? My suggestion would be
something like this:

Files: src/ZSTD/*
Copyright: <as in the ZSTD files>
License: BSD or GPL-2
URL: ...

Files: *
Copyright: 2019 Travers Ching
License: <your license>
