• Add /insertr.js endpoint to serve JavaScript library from API server
• Implement demo gate auto-injection for sites without existing gates
• Add dynamic site ID injection using per-demo configuration files
• Fix CORS middleware to support localhost origins on any port
• Update demo commands to use individual insertr.yaml configs
• Resolve content persistence issues by matching site IDs between injection and enhancement
• Enable complete edit/save workflow for demo sites with proper namespace isolation
🏗️ **Major Architecture Refactoring: Separate CLI + Server → Unified Binary**
**Key Changes:**
✅ **Unified Binary**: Single 'insertr' binary with subcommands (enhance, serve)
✅ **Preserved Database Architecture**: Maintained sophisticated sqlc multi-DB setup
✅ **Smart Configuration**: Viper + YAML config with CLI flag precedence
✅ **Updated Build System**: Unified justfile, Air, and npm scripts
**Command Structure:**
- `insertr enhance [input-dir]` - Build-time content injection
- `insertr serve` - HTTP API server (dev + production modes)
- `insertr --config insertr.yaml` - YAML configuration support
**Architecture Benefits:**
- **Shared Database Layer**: Single source of truth for content models
- **Flexible Workflows**: Local DB for dev, remote API for production
- **Simple Deployment**: One binary for all use cases
- **Better UX**: Consistent configuration across build and runtime
**Preserved Features:**
- Multi-database support (SQLite + PostgreSQL)
- sqlc code generation and type safety
- Version control system with rollback
- Professional API endpoints
- Content enhancement pipeline
**Development Workflow:**
- `just dev` - Full-stack development (API server + demo site)
- `just serve` - API server only
- `just enhance` - Build-time content injection
- `air` - Hot reload unified binary
**Migration:** Consolidated insertr-cli/ and insertr-server/ → unified root structure
