test(smoke): give the smoke-aws-docs fixture a readiness probe

health-readiness.smoke.test.ts asserts no RUNNING server lacks a
healthCheck.tool. The smoke suite's own shared fixture had none, so the suite
reported its own scaffolding as a fleet regression — and because the fixture is
in the PROTECTED set of clean-smoke-resources.ts, it is long-lived and failed
that assertion on every run.

Mirrors the production aws-docs probe (same package): search_documentation with
a phrase, 300s interval since the call leaves the cluster.

Verified live: with this applied, "every RUNNING server has a readiness probe
configured" passes.
