WebMiliastra Nodes Editor MCP Server

# Project format A project folder contains `manifest.json` plus graph files referenced by the manifest entries. The MCP server reads and writes this folder structure. Example layout: ``` project/ manifest.json server/entity/default/my-graph.json client/boolean-filter/default/check-flag.json ``` Manifest essentials: - `manifest.project.id` and `manifest.project.name` identify the project. - `manifest.graphs[]` contains entries with `graphId`, `name`, and `path`. - `path` is relative to the project root and should end with `.json`. The server only enforces basic validation. The editor may expect more metadata (groups, appVersion, etc.) depending on your workflow.
