feat: add lyrics column layout with scroll browsing and calendar inli…

• Add 3-line synced lyrics column (prev/current/next) beside compact music player when LRC lyrics are available; toggled via Settings or tapping the inline lyric line
• Lyrics scroll browsing: mouse scroll gesture moves through lines with a 2-second auto-snap back; uses NSEvent local monitor to reliably capture scroll events behind SwiftUI content layers
• Calendar moves into the right panel (replacing lyrics column) toggled from a new capsule button in BoringHeader; separator line collapses the panel
• Lyrics disk cache at ~/Library/Application Support/boringNotch/lyrics_cache.json to avoid redundant LRCLIB fetches; auto-retry once on network failure
• Retry button shown in lyrics column when lyrics are genuinely unavailable
• Add lyricsColumnLayout key to Constants and sub-toggle in Settings

Looks good overall. Instead of enabling lyrics by default on closed notch, could you add a top toggle button (similar to the calendar one) to show/hide lyrics, and reuse the calendar icon for this?

I should be able to add that but don't know if that would be a really good ux decision. Adding an extra click, might prevent users in general to not use the feature entirely (on the flip side can reduce unneccesary calls to fetch lyrics)
