Pinned sources, See-all home, CI health

Sources

• Pin sources to top in the picker — long-press or tap the pin icon
• Search inside the picker when you have 10+ installed
• Installed tab grouped by repo in collapsible cards
• New Discover tab in /sources with a curated directory
• Remote source health — CI in the providers repo runs every 6h and flags broken sources in-app
• Update button works again — bypasses CDN cache + shows a result snackbar

Home

• "See all" on each section opens a paginated grid for that catalog
• Title language preference: Original / English / Both

Settings

• Credits screen for testers + contributors
• Noman added to Developers

Cleanup

• MangaDex removed (SPA + API gaps — couldn't scrape reliably)
