plugin validator is not suitable for a single plugin

[ozsay]

The readme specifies:

For a single plugin, move your plugin folder contents to the repository root, keep one .cursor-plugin/plugin.json, and remove .cursor-plugin/marketplace.json.

but the validator is checking for marketplace.json first thing

plugin-template/scripts/validate-template.mjs

Line 251 in 8cbb164

const marketplacePath = path.join(repoRoot, ".cursor-plugin", "marketplace.json");
