ci(doctests): skip the qt-api-events spec, which builds a provider module

This PR removes `logos-cpp-generator --provider-header`. The watcher fixture in
doctests/cpp-sdk-qt-api-events.test.yaml is `interface: "provider"`, so
logos-module-builder reaches "generating provider dispatch (qt_watcher_module)"
and the generator refuses:

    Error: --provider-header was removed.

That one build failure cascades through the rest of the spec (install, load,
subscriptionAccepted, greetThrough, greetedCount, lastGreeted), which is the
whole of the red on both ubuntu-latest and macos-latest. notifier_module is
`interface: universal` and builds fine.

Skipped rather than rewritten. The replacement shape that keeps the Qt-typed
dependency wrappers without the retired provider dispatch is
`interface: universal` + `codegen.consumer_api_style: "qt"`, and
logos-module-builder master does not carry that key yet — while this spec pins
the builder to master. It arrives with the B4 stack.

The spec file is kept and annotated, not deleted, because it covers two things
nothing else does: the Qt-TYPED wrapper emission (separately generated code
from the lp path, so lp-path specs cannot catch a bug in it) and a subscription
made from onInit() before the dependency is reachable. Both are UNTESTED until
this is restored — a known, accepted gap recorded in the spec header and in the
workflow.
