chore(ios): add WebTermTests unit-test bundle target (W3 coordination point)

project.yml gains a bundle.unit-test target hosted by the app, wired to all
5 local packages (TestSupport test-doubles included) so T-iOS-11..14 VM tests
run via xcodebuild test. Coverage gate still counts only the 4 packages (§9).
