- Add appearance settings: font size, time display format, entry images toggle, reading time toggle
- Add keyboard shortcuts dialog (? key) with all keybindings documented
- Add extended vim shortcuts: gg, G, n/N (next/prev unread), Ctrl+h/l (panel focus)
- Add command palette shortcut (⌘K) to shortcuts dialog
- Add icon URL fields for folders and custom feeds (DB + queries + settings UI)
