test: wire test/framework packages into unit tests and coverage

The test/framework tree that #1188 introduces has no Makefile entry, so its
packages would not run under make test-unit and would be absent from the
coverage comparison. Wire the package set in before any helper moves land, so
each follow-up move arrives with test execution and coverage already in place.

The importas aliases for the planned framework packages are added in the same
change: golangci-lint ignores entries for packages that do not exist yet, so
the later moves do not each have to touch the lint config.

Part of #1188

+//   - R4: test/framework/epp/harness may import anything; it is imported
