…rable (LabsCrypt#643) - Replace the hardcoded 60s sweep interval with a configurable interval reading process.env.MEMORY_CACHE_SWEEP_MS (defaulting to 60_000ms). - Store the interval handle and export stopMemoryCacheSweep() to prevent leaking timers across Vitest runs. - Call stopMemoryCacheSweep() in disconnectRedis() for symmetry. - Document MEMORY_CACHE_SWEEP_MS in .env.example. - Expose startMemoryCacheSweep() and stopMemoryCacheSweep() in unit tests to test configuration and cleanup.
