Landing page v0.2.0 redesign

[jamiepine]

Summary

Complete redesign of the landing page to reflect the v0.2.0 multi-engine release.

• Multi-engine messaging — replaced all Qwen-specific copy with multi-engine language across hero, meta tags, and feature descriptions
• GitHub star count — server-side fetched via /api/stars route with 10-min cache, displayed as a Spacedrive-style badge in the navbar
• Model cards section — replaced "Why Voicebox exists" manifesto with cards for all 4 TTS engines (Qwen3-TTS, Chatterbox, Chatterbox Turbo, LuxTTS) with specs and capabilities
• Voice Creator section — new section with animated 3-tab UI (Upload, Microphone, System Audio) featuring waveform background animation matching the real app's recording UI
• Responsive ControlUI — horizontal scroll profile cards on mobile, stacked layout, scroll-to-active profile with separate mobile/desktop refs, sticky header with gradient fade overlay
• iOS Safari audio fix — unlock WaveSurfer's actual media element on user gesture to prevent NotAllowedError
• Linux download enabled — was greyed out "Coming soon", now active with dynamic release link
• GPU support copy — updated to include ROCm, Intel Arc, and DirectML
• UI polish — pointer-events-none on all animations, accent play button, fixed-height profile cards, mobile edge fades, hero logo blend fix, grain overlay disabled (tile seams)
