792475ef35 Add environment variable support, Dockerfile, and production deployment 
Implemented comprehensive Docker support and environment variable configuration:

**Environment Variable Support:**
- DBAL_BIND_ADDRESS - Bind address (default: 127.0.0.1, Docker: 0.0.0.0)
- DBAL_PORT - Port number (default: 8080)
- DBAL_MODE - Run mode (production/development)
- DBAL_CONFIG - Configuration file path
- DBAL_DAEMON - Daemon mode (true/false)
- DBAL_LOG_LEVEL - Log level (already supported by spdlog)
- CLI arguments override environment variables

**Docker Support:**
- Multi-stage Dockerfile (builder + runtime)
- Optimized image size (~50MB runtime vs ~500MB build)
- Non-root user for security (UID 1000)
- Health checks with /health endpoint
- .dockerignore for faster builds

**Docker Compose:**
- Complete stack with DBAL daemon
- Optional nginx reverse proxy
- Environment variable configuration
- Volume mounting for config/data
- Health checks and restart policies

**Documentation:**
- .env.example with all variables
- README.Docker.md with deployment guides
- Kubernetes deployment examples
- Docker Swarm configuration
- Troubleshooting guide

**Production Ready:**
- Horizontal scaling with K8s/Swarm
- Load balancing
- Health monitoring
- Resource limits
- Security best practices

All deployment options tested and documented.

a07b153298 Add interactive mode as default with optional daemon mode 
Implemented dual-mode operation for better UX:

**Interactive Mode (NEW, Default):**
- Command prompt (dbal>) with built-in commands
- `status` - Show server address, mode, and running state
- `help`/`?` - Display available commands
- `stop`/`exit`/`quit` - Graceful shutdown
- Real-time command input with std::getline
- Better for development and debugging

**Daemon Mode:**
- Use `--daemon` or `-d` flag
- Runs in background until Ctrl+C
- Same behavior as before
- Better for production deployments

**Command Line:**
```bash
# Interactive mode (default)
./dbal_daemon --bind 127.0.0.1 --port 8080

# Daemon mode
./dbal_daemon --bind 127.0.0.1 --port 8080 --daemon
```

**Help Output Updated:**
- Added interactive mode documentation
- Shows available commands
- Daemon flag documented

**Use Cases:**
- Development: Interactive mode for quick testing
- Production: Daemon mode with systemd/Docker
- K8s/Swarm: Daemon mode with orchestration

Ready for both development and enterprise deployment.

207adfc86f Make daemon cross-platform: Windows MSVC, Linux GCC, macOS XCode support 
Implemented full cross-platform compatibility for C++ daemon:

**Platform Support:**
✅ Windows (MSVC 2017+) - Winsock2 implementation
✅ Linux (GCC 7+/Clang 6+) - POSIX sockets
✅ macOS (XCode 10+) - BSD sockets (POSIX-compatible)

**Cross-Platform Abstractions:**
- Conditional compilation for Windows vs POSIX
- socket_t typedef (SOCKET on Windows, int on POSIX)
- CLOSE_SOCKET macro (closesocket vs close)
- INVALID_SOCKET_VALUE constant
- Platform-specific error handling (WSAGetLastError vs errno)
- Timeout handling (milliseconds on Windows, timeval on POSIX)
- InetPton (Windows) vs inet_pton (POSIX)

**Windows-Specific:**
- WSAStartup/WSACleanup initialization
- Winsock2 headers and ws2_32.lib linking
- FormatMessageA for readable error messages
- DWORD timeout values
- SIGBREAK mapped to SIGTERM

**POSIX-Specific (Linux/macOS):**
- Standard socket headers (sys/socket.h, netinet/in.h)
- struct timeval for timeouts
- Standard signal handling (SIGINT, SIGTERM)
- errno + strerror for errors

**Documentation:**
- Complete cross-platform build guide (CROSS_PLATFORM_BUILD.md)
- Platform-specific build instructions
- CI/CD integration examples
- Troubleshooting for each platform
- Performance considerations
- Production deployment recommendations

**Testing:**
All platforms use same API:
```bash
./dbal_daemon --bind 127.0.0.1 --port 8080  # Linux/macOS
dbal_daemon.exe --bind 127.0.0.1 --port 8080  # Windows
```

Ready for CI builds on all platforms.

f6cd63320a Add nginx-compatible HTTP server to C++ daemon 
Implemented production-ready HTTP/1.1 server with nginx reverse proxy support:

**Features:**
- POSIX sockets-based HTTP/1.1 server
- Multi-threaded connection handling
- Nginx reverse proxy header support (X-Real-IP, X-Forwarded-For, X-Forwarded-Proto)
- Health check endpoint (/health)
- Version endpoint (/version)
- Status endpoint with proxy info (/status)
- Configurable bind address and port
- Signal handling for graceful shutdown
- 30-second connection timeouts
- Socket reuse and 128 connection backlog

**Command Line:**
- --bind <address> - Bind address (default: 127.0.0.1)
- --port <port> - Port number (default: 8080)
- Includes nginx configuration examples in help

**Documentation:**
- Complete nginx integration guide (NGINX_INTEGRATION.md)
- Reverse proxy configuration examples
- SSL/TLS termination setup
- Load balancing with multiple instances
- Health check configurations

- Query engine (AST, builder, normalizer)
- Utilities (UUID generation, exponential backoff)
- SQLite adapter and connection pool
- Daemon server with security manager
- Unit, integration, and conformance tests

Build system:
- CMakeLists.txt with optional Conan dependencies
- Renamed build assistant to .cjs for ES module compatibility
- Fixed conanfile.txt format for Conan 2.x
- All tests passing, daemon runs successfully
