Full MVP: workspace layout, visual refresh, PWA, production deploy

Major changes since initial commit:

Schema: version branching (parentVersionId, branchLabel), share links,
guest comments, track status enum (sketch/in_progress/final/released),
track sections, cover art for projects and tracks.

API: 29+ endpoints — auth, projects, tracks, versions, comments, share
links (public + management), uploads (cover), activity feed, onboarding
demo seed. Email templates in German with brand styling.

Web: SvelteKit 5 workspace layout with persistent sidebar, breadcrumb
top-bar, collapsible right panel. SoundCloud-style waveform player with
round play button, avatar comment markers, keyboard shortcuts (Space/JKL/C).
Full German UI. Cover art with gradient fallback. Track status pills.
Activity feed dashboard. Welcome modal with demo-seed trigger. Landing
page with 7-section scroll layout. Login on /login. Public /listen/:token
page for guest feedback.

Visual: Inter Variable font, Magenta→Orange gradient accent, warm dark
neutrals, Lucide-style inline SVG icon set, spring animations on modals,
glass-effect toasts, responsive from 360px to 2560px+.

PWA: manifest, service worker, icons, iOS/Android installable.

Production: adapter-node, server-side API proxy hook, docker-compose with
Postgres + MinIO + auto-migration + health checks. Env example included.
