fix: use path instead of url for skill metadata API call (#22)

The `cmdUpdate` function was passing a relative path to `apiRequest`
using the `url` property, but `url` expects a full URL. When `url` is
provided, it's used as-is without combining with the registry base URL.

This caused "Failed to parse URL from /api/v1/skills/<slug>" errors
when updating skills that don't have a local fingerprint match.

Changed to use `path` property which correctly combines with the
registry base URL via `new URL(args.path, registry)`.
