- Fix component name mismatch: "redis" -> "cache" in bootstrap_manager
- Add cache_health_check() function to verify Valkey is responding
- Add health check loop after starting cache (12s wait with PING test)
- Ensures cache is ready before proceeding with bootstrap
This fixes the issue where botserver would hang waiting for cache
connection because the cache component was never started.
