fix: add index.mjs wrapper so default import works without import attributes

Previously the '.' export pointed directly at registry.json, requiring
consumers to write `import x from '@framers/agentos-skills/registry.json'
with { type: 'json' }` (Node 22+) or the deprecated assert syntax.
Bare `import x from '@framers/agentos-skills'` failed with
'needs an import attribute of type: json'.

The new index.mjs reads registry.json via fs at runtime so it works on
every supported Node version without flags or attributes.
