fix: remove skeleton-only entries from changelog

Per review feedback, changelog entries that only affect the skeleton
template and won't impact existing storefronts should not be included.
Removes gift card accessibility, robots.txt defaults, and store linking
notice entries from 2026.1.1 and 2026.1.2. Updates release titles to
reflect remaining content.
