- Add packages/cache with CacheDriver interface (get/set/del/exists/clear) - Implement MemoryDriver (Map-based, TTL support) - Implement RedisDriver (ioredis, lazyConnect, error handling) - Implement CacheManager with manual fallback (Redis first, memory as backup) - Add createCache factory function for easy initialization - All dependency versions pinned per CLAUDE.md Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>beauty-auth
