fix: commit missing paraglide feed message JS files (were gitignored, needed force-add)

New feed_*.js and nav_feed.js outputs from npm run paraglide were not tracked
because src/lib/paraglide/.gitignore ignores everything by default. Force-add
them so CI can run svelte-check without running paraglide compile first.

Also include recentlyUpdatedBooks fallback improvements from working tree.
