feat: v1.13.0 — SVG Logo, Marquee, Player UX, Global Shortcuts fix

### Added
- SVG logo with theme-adaptive gradient in sidebar (full wordmark + P-icon for collapsed state)
- Player bar: song title/artist marquee scroll on overflow
- Player bar: live volume percentage tooltip on slider hover

### Changed
- Sidebar collapse button moved to right-edge hover tab
- Player bar: fixed 320px track info width, increased waveform margins
- Settings: Server tab opens by default
- Crossfade: experimental badge removed (stable)
- Help page: Lyrics/Keybindings/Font entries added, theme count corrected

### Fixed
- Global shortcuts double-fire (Rust-side ShortcutMap idempotency fix)
- W98 theme: comprehensive contrast fixes for navy hover backgrounds
- Help page: removed orphaned translation key under Playback
