Stabilize azure-validate deployment-validation tests by terminating on validate invocation

[Copilot]

Integration tests for azure-validate were intermittently failing because deployment-validation scenarios could continue past the validation handoff and reach deployment commands. The expected behavior is to stop once validation begins (or azure-validate is invoked), before any deploy path executes.

• What changed

  • Updated tests/azure-validate/integration.test.ts in the deployment-validation suite to early-terminate not only on validation/deployment commands, but also when the azure-validate skill itself is invoked.
  • Applied this consistently across:
    • static whiteboard web app
    • static portfolio website
    • containerized web app on Container Apps

• Why this addresses the issue

  • The tests now stop at the intended orchestration boundary (azure-prepare → azure-validate) instead of relying solely on command-level detection, which reduces non-deterministic drift into deployment behavior.

• Representative change
