Initial implementation of qobuz-qt
- Rust backend (qobuz-backend static lib): Qobuz API client (reqwest/tokio), Symphonia audio decoder, CPAL audio output, extern "C" FFI bridge - Qt 6 frontend mirroring spotify-qt layout: toolbar with playback controls, left library dock, central track list, right search panel - Auth: email/password login with MD5-signed requests; session token persisted via QSettings - Playback: double-click a track → Rust fetches stream URL → Symphonia decodes → CPAL outputs to default audio device - Dark Fusion palette matching spotify-qt feel Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
