v0.4.0: Remove free tier, add public demo endpoint with watermark
- Remove free account signup flow entirely - Add POST /v1/demo/html and /v1/demo/markdown (public, no auth) - Demo: 5 requests/hour per IP, 50KB body limit, watermarked PDFs - Landing page: interactive playground replaces 'Get Free API Key' - Pricing: Demo (free) + Pro (€9/mo), no more Free tier - /v1/signup returns 410 Gone with redirect to demo/pro - Keep /v1/recover for existing Pro users - Update JSON-LD, API discovery, verify page text
