v2.2.0

• feat: Atom feed entries restructured for scanability — <hr> separators between description, capture date, camera/lens, and tags sections; 📆/📷/🏷️ icons on each section; tags now also rendered as visible #tag text (previously only <category> XML elements)
• chore: one-time script (scripts/strip-title-periods.js) to strip trailing periods from older auto-generated sidecar titles, matching the v2.0.0 title-generation change (text before first period, not first word)
