add meta descriptions to all shop pages

Product pages: first 155 chars of description, stripped of HTML, truncated on word boundary.
Collections: contextual description based on collection type.
Content pages (about, delivery, privacy, terms): from hero_description text.
Contact: static description.
Home falls through to site_description from settings (already in layout).
