v0.1.52

What's Changed

Automatic TLS certificate hot-reloading

ColdBrew now automatically watches TLS cert/key files for changes and reloads them without requiring a service restart. This is powered by cloudflare/certinel using fsnotify for event-driven file watching.

• Zero-downtime certificate rotation for Kubernetes (cert-manager, Vault)
• Works with symlink-based rotation out of the box
• Watcher errors trigger graceful shutdown so the process can be restarted by the orchestrator
