Retry hydration after delayed service readiness.

If whenReady remains pending beyond the five-second timeout, hydrateFromK8sToken() can call getToken() before tokenInfo is set. getToken() then throws, and extension activation has no retry path. Defer or retry hydration after readiness, and add a delayed-readiness regression test.

hydrateFromK8sToken and its interaction with getToken so hydration is retried or
deferred when githubService.whenReady exceeds the five-second race, ensuring
tokenInfo is initialized before token access. Add a regression test covering
delayed service readiness and successful hydration after readiness.
