Deezy v0.2.1

Added

• Playlist search & download – New "Playlists" tab in search view to find and browse playlists, view tracks, and batch-download all tracks with one click

Fixed

• i18n translation loading – Fixed race condition where translation keys (e.g. search.tabs.playlists) were displayed as raw text instead of translated strings. Now properly awaits locale initialization using waitLocale() before rendering UI
• Settings toggle buttons – Fixed corrupted toggle switches for notifications, search history, and system tray where the purple circle overlapped text and buttons were non-functional. Restructured toggle component with separate wrapper for proper layout and click handling

Changed

• Resolve all Clippy warnings: remove needless borrow in commands.rs, use .is_multiple_of() in download.rs, derive Default for FolderStructure in settings.rs
