feat: add CI/CD pipeline with automated deployment (#2)

Implement continuous integration and deployment workflows:
- CI workflow runs linting, type checks, and builds on every push and PR
- Deployment workflow automatically deploys to Dokku when code is pushed to main
- Deploys to worlddriven-webapp Dokku app via deployment webhook
- Includes health check verification after deployment
