Declare HttpResponse so .then callbacks resolve at runtime

matches() threw "Undefined identifier [HttpResponse]" on the first
request. The runtime resolves the type of every .then callback parameter
against the enclosing scope, so HttpResponse has to be declared in any
file that defines one — even though it is never referenced by name.

Compiling does not catch this, which is why CI was green. Both shipping
reference plugins carry the same seemingly-unused declaration.

Also fixes the identical latent failure in core.checkUpdate.
