v1.1.0 — RSS feed, PWA, lesson comments, progress tracking + streaks

RSS Feed
- /feed.xml proxies the Anchor feed under the site's canonical domain
- Rewrites channel <link> and atom:link self-ref to the site URL
- Served with 30-min Cache-Control, reuses the existing episode cache

PWA
- vite-plugin-pwa installed; Workbox service worker auto-generated on build
- manifest.json inlined in vite.config.ts (name, icons, theme, standalone)
- pwa-192.png and pwa-512.png generated from existing book_icon.png
- StaleWhileRevalidate for /api/episodes and /api/questions; CacheFirst for images
- API, feed.xml, and uploads routes excluded from navigate fallback

Lesson Comments
- Import and wire StudySectionComments into ColossiansStudySectionPage
- Replaces the CommunityBoard in the Lesson Discussion section
- All routes and moderation already existed; only the render was missing

Progress Tracking + Streaks
- Mark-complete handler now records lastStudiedDate, currentStreak, longestStreak on the user record
- Streak increments on consecutive calendar days, resets on a gap
- /api/study-account/overview now returns streak fields
- Account page: 4-stat summary row (notes, streak 🔥, longest streak, member since)
- Per-study progress bars showing completedLessons/totalLessons with gold → green fill at 100%
