Add skill name resolution and enhanced install confirmation in Skills Hub

- Introduced a new function `_resolve_short_name` to convert short skill names to full identifiers, improving user experience during skill installation.
- Updated the `do_install` function to utilize the new resolution method for identifiers without slashes, ensuring accurate skill fetching.
- Enhanced the install confirmation process to include a disclaimer about third-party skills, emphasizing user responsibility and security awareness.
