test(service-cluster-redis): de-flake Redis wiring test (hoist cold imports) (#1495)

The "Redis driver — wiring" tests did `await import('./index.js')` +
`await import('@objectstack/service-cluster')` inside the test body, under the
default 5000ms timeout. On a cold/slow CI runner the one-time module load
exceeded 5s and the first test failed with "Test timed out in 5000ms" (the
second only passed because the first warmed the module cache) — an
intermittent red on Test Core unrelated to any product change.

Hoist both to top-level static imports: `import './index.js'` still registers
the 'redis' driver as a side-effect at module eval, and `defineCluster` is a
normal named export. The import cost now lands once at file load, outside any
per-test timeout. Test assertions are unchanged.
