- Move draft recovery from inline header to prominent banner below header
- Style draft banner with blue info colors and slide-down animation
- Fix draft persistence by clearing localStorage on restore/dismiss
- Call beforeNavigate at top level for proper Svelte 5 lifecycle
- Add keyboard shortcut (Cmd/Ctrl+S) and navigation guard effects
- Update AutoSaveStatus to support both old stores and new reactive props
