Verify Transport

1. nitrostack-py validate
2. HTTP debug: NITROSTACK_HTTP_DEBUG=1 MCP_TRANSPORT_TYPE=http nitrostack-py dev
3. Hit GET http://localhost:3000/mcp/health
4. Inspector URL is http://localhost:3000/mcp without a trailing slash
5. Auth off unless OAuth is configured — otherwise Inspector POSTs /register and you see Cannot POST /register
6. Do not log to stdout on stdio transport
7. TRUSTED_PROXIES must include your load balancer if you rely on X-Forwarded-Host / X-Forwarded-Proto
