feat: Add Phase 0 deployment infrastructure (CRITICAL)

Phase 0.1: Deployment Router
- Create deployment module with DeploymentRouter
- Support internal (GB Platform) and external (Forgejo) deployment
- Add proper error handling and result types

Phase 0.2: Forgejo Integration
- Create ForgejoClient for repository management
- Implement git push functionality with git2
- Add CI/CD workflow generation for HTMX, React, Vue apps
- Support custom domains and automated deployments

Phase 0.3: Backend preparation
- Add deployment types and configuration structures
- Prepare integration with orchestrator
