Pull Request Overview

This PR adds support for outputting generic alternates (alternates without a language) in page metadata, extending the existing language-only alternate support.

Key Changes

• Enhanced canonical URL handling to support both relative and absolute URLs using URL.canParse()
• Modified the alternates reduction logic to collect both language and generic alternates
• Attempted to output generic alternates through the metadata types field
