Formbricks no longer deploys to Vercel and does not support it for
self-hosters. This removes all Vercel-specific deployment config,
environment variables, and infrastructure references from the codebase.
- Delete vercel.json and .vercelignore
- Remove VERCEL_URL env var from env.ts, constants.ts, getPublicUrl.ts
- Remove X-Vercel-IP-Country header from v1 and v2 response API routes
- Remove VERCEL / VERCEL_URL from turbo.json build env passthrough
- Update .env.example and docker-compose.yml comments
- Update sentry.edge.config.ts comment
- Remove VERCEL_URL from license.test.ts and getPublicUrl.test.ts mocks
- Update docs to remove Vercel deployment references
