Add kubefwd to Development Tools

[cjimti]

kubefwd solves a common pain point in Kubernetes local development: accessing multiple cluster services without port conflicts.

What makes it awesome:

• Unique IPs per service - Each service gets its own 127.x.x.x address, so multiple services can use port 80, 443, 3306, etc. simultaneously
• Service name resolution - Automatically manages /etc/hosts so you can use curl http://api-service:8080 locally, exactly like in-cluster
• Interactive TUI - Real-time traffic monitoring, pod logs, and service status in one view
• Auto-reconnect - Handles pod restarts gracefully with exponential backoff
• 4,000+ stars, 30 contributors, actively maintained

Complements existing tools like Telepresence and mirrord by focusing on simple, bulk port forwarding without code injection or proxying.
