refactor(client): name one assembly package for the carrier types

A business package imported the Remote assembly for `ctx.remote` and the
Connection plugin for the wire types it passes around. The assembly now
re-exports the carrier's Client-facing types, so a business package names one
package. The re-export is type-only: the carrier's runtime values keep their
own module edge, since inlining them here would duplicate the carrier inside
the assembly bundle.

Four surfaces that had no Remote assembly dependency declare one now.
