Add OpenClaw and NanoClaw scripts for Hetzner Cloud (#6)
Fills the remaining 2 gaps in the agents x clouds matrix: - hetzner/openclaw.sh: provisions Hetzner server with OpenClaw gateway + TUI - hetzner/nanoclaw.sh: provisions Hetzner server with NanoClaw WhatsApp agent Matrix is now 100% complete (3 agents x 2 clouds = 6/6 implemented).
