Fix nemotron-super tool_call_parser; auto-clear WireGuard hostname from known_hosts
- hyperstack-vm.toml: set tool_call_parser=llama3_json for nemotron-super so vLLM
accepts tool_choice requests from opencode; model won't spontaneously call tools
so the vLLM 0.17.1 token_ids crash in llama3_json won't trigger
- hyperstack.rb: wait_for_ssh now also removes the WireGuard hostname
(hyperstack.wg1) from known_hosts alongside the IP, preventing
StrictHostKeyChecking failures across VM recreates
