Tangle emacs-edit and lisp-utils skills, update package exports

- Add vector search exports (get-embedding, cosine-similarity, semantic-search)
- Add tool permissions exports to package.lisp
- Add tool-permissions-tests to asdf test system
- Tangled org-skill-emacs-edit.org and org-skill-lisp-utils.org
- Fixed emacs-edit-tests.lisp (was missing closing paren)
- Now 77/77 tests passing
