fix: don't share middleware backing array between requesters (#8)

* fix: don't share middleware backing array between requesters

With appended to the parent's middleware slice in place. When the parent
chain had spare capacity, derived requesters shared the same backing array
and a later With overwrote the middleware of an earlier one, so a requester
could send another requester's credentials.

With now builds its own chain, and New copies the caller's variadic slice so
Use cannot write into it either.

* test: describe what the With regression test asserts
