Fix npm package deployment and usage documentation

🔧 Resolve npmjs deployment issue:
- Add npm global installation guide (npm install -g @ironclads/incus-mcp)
- Update Claude Desktop configuration with two options
- Fix mcp-config-example.json to use global binary
- Update CLAUDE.md with correct remote server list (removed lambda)
