Add manifest URL for this plugin entry

This new entry is the only src/*.json plugin without a manifest, but the release pipeline still runs bun run sync first (.github/workflows/release.yml), and syncExistPlugins in scripts/sync.ts unconditionally calls fetch(pluginManifest.manifest) for every plugin file. In this state, crossfin-mcp always hits the error path and cannot participate in normal manifest-based syncing/consumption, so users of the index won’t get a usable install target unless a manifest (or explicit MCP-specific handling) is added.
