The MCP Registry requires the npm package to declare `mcpName` matching
the namespace in server.json. This is the cross-link that proves the
owner of the npm package and the owner of io.github.vatnode/* are the
same entity.

Bumped 0.2.0 → 0.2.1 (no code changes beyond the manifest fields and
the VERSION constant in src/index.ts kept in sync with package.json).
