The plugin version pins to packages/runtime/package.json, but plugin.json
(1.60.0) and marketplace.json (plugins[0] 1.60.0, metadata 1.57.3) had
rotted behind the runtime package (1.60.2), so check:plugin-skills was
failing on main.
handleVersionSync previously managed only plugin.json.version and
marketplace plugins[0].version, leaving marketplace metadata.version
unmanaged and free to drift independently. Extend it to track
metadata.version against the runtime version too, and re-run the sync to
bring all three fields to 1.60.2.
