excalidraw-location-mcp-servers-not-infra

Excalidraw MCP server lives at /opt/mcp-servers/excalidraw-mcp/, not /opt/infra/ as documented in architecture.md. This matters for path-dependent operations like upgrades, backup targeting, and volume mounts. Pattern: MCP servers live at /opt/mcp-servers/, infrastructure services live at /opt/infra/.
