Description: # FluxMQ Python Library
        
        A flexible, protocol-agnostic messaging library for Python applications, providing a unified interface for different messaging protocols.
        
        ## Overview
        
        FluxMQ is a messaging abstraction layer that allows applications to use different messaging protocols (NATS, MQTT, etc.) through a consistent interface. This makes it easy to switch between messaging systems without changing application code.
        
        Key features:
        - Protocol-agnostic messaging interface
        - Support for multiple transport implementations (NATS, MQTT)
        - Asynchronous and synchronous APIs
        - Request-reply pattern support
        - Standardized topic naming conventions
        - Consistent status reporting
        
        ## Installation
        
        ```bash
        pip install fluxmq
        ```
        
        Or install from source:
        
        ```bash
        git clone https://github.com/yourusername/fluxmq-py.git
        cd fluxmq-py
        pip install -e .
        ```
        
        ## Dependencies
        
        - Python 3.7+
        - For NATS support: `nats-py`
        - For MQTT support: `paho-mqtt`
        - For Zenoh support: `zenoh` (install with `pip install fluxmq[zenoh]`)
        
        ## Quick Start
        
        ### Basic Usage with NATS
        
        ```python
        import asyncio
        from fluxmq.adapter.nats import Nats, NatsTopic, NatsStatus
        from fluxmq.message import Message
        
        async def main():
            # Initialize transport, topic, and status
            transport = Nats(servers=["nats://localhost:4222"])
            topic = NatsTopic()
            status = NatsStatus()
            
            # Connect to the messaging system
            await transport.connect()
            
            # Subscribe to a topic
            async def message_handler(message: Message):
                print(f"Received message: {message.get_data_as_string()}")
                
            await transport.subscribe("example.topic", message_handler)
            
            # Publish a message
            await transport.publish("example.topic", "Hello, world!")
            
            # Request-reply pattern
            response = await transport.request("example.service", {"action": "get_data"})
            print(f"Response: {response.get_data_as_string()}")
            
            # Clean up
            await transport.close()
        
        if __name__ == "__main__":
            asyncio.run(main())
        ```
        
        ### Using MQTT
        
        ```python
        import asyncio
        from fluxmq.adapter.mqtt import MQTT, MQTTTopic, MQTTStatus
        from fluxmq.message import Message
        
        async def main():
            # Initialize transport, topic, and status
            transport = MQTT(host="localhost", port=1883)
            topic = MQTTTopic()
            status = MQTTStatus()
            
            # Connect to the messaging system
            await transport.connect()
            
            # Subscribe to a topic
            async def message_handler(message: Message):
                print(f"Received message: {message.get_data_as_string()}")
                
            await transport.subscribe("example/topic", message_handler)
            
            # Publish a message
            await transport.publish("example/topic", "Hello, world!")
            
            # Clean up
            await transport.close()
        
        if __name__ == "__main__":
            asyncio.run(main())
        ```
        
        ### Using Zenoh
        
        ```python
        import asyncio
        from fluxmq.adapter.zenoh import Zenoh, ZenohTopic, ZenohStatus
        from fluxmq.message import Message
        
        async def main():
            # Initialize transport, topic, and status
            transport = Zenoh()  # Default configuration connects to local Zenoh router
            topic = ZenohTopic()
            status = ZenohStatus()
            
            # Connect to the messaging system
            await transport.connect()
            
            # Subscribe to a topic
            async def message_handler(message: Message):
                print(f"Received message: {message.get_data_as_string()}")
                
            await transport.subscribe("example/topic", message_handler)
            
            # Publish a message
            await transport.publish("example/topic", "Hello, world!")
            
            # Request-reply pattern
            response = await transport.request("example/service", {"action": "get_data"})
            print(f"Response: {response.get_data_as_string()}")
            
            # Clean up
            await transport.close()
        
        if __name__ == "__main__":
            asyncio.run(main())
        ```
        
        ## Architecture
        
        FluxMQ consists of several key components:
        
        ### Transport
        
        The `Transport` interface defines the core messaging operations:
        - `connect()`: Connect to the messaging system
        - `close()`: Close the connection
        - `publish()`: Publish a message to a topic
        - `subscribe()`: Subscribe to a topic with a message handler
        - `unsubscribe()`: Unsubscribe from a topic
        - `request()`: Send a request and wait for a response
        - `respond()`: Respond to a request message
        
        Implementations:
        - `Nats`: NATS implementation
        - `MQTT`: MQTT implementation
        - `Zenoh`: Zenoh implementation
        
        ### Message
        
        The `Message` class represents a message in the system:
        - `data`: The message payload
        - `reply`: Optional reply subject for request-reply patterns
        - `headers`: Optional headers associated with the message
        
        ### Topic
        
        The `Topic` interface provides standardized topic naming conventions:
        - `status()`: Topic for service status updates
        - `configuration()`: Topic for service configuration
        - `error()`: Topic for error messages
        - And many more...
        
        Implementations:
        - `StandardTopic`: Base implementation with configurable prefix
        - `NatsTopic`: NATS-specific implementation
        - `MQTTTopic`: MQTT-specific implementation
        - `ZenohTopic`: Zenoh-specific implementation
        
        ### Status
        
        The `Status` interface provides standardized status values:
        - `connected()`: Connected status
        - `ready()`: Ready status
        - `active()`: Active status
        - `paused()`: Paused status
        - `error()`: Error status
        
        Implementations:
        - `StandardStatus`: Base implementation
        - `NatsStatus`: NATS-specific implementation
        - `MQTTStatus`: MQTT-specific implementation
        - `ZenohStatus`: Zenoh-specific implementation
        
        ## Advanced Usage
        
        ### Synchronous API
        
        For applications that can't use asyncio, FluxMQ provides a synchronous API:
        
        ```python
        from fluxmq.adapter.nats import SyncNats
        from fluxmq.message import Message
        
        def message_handler(message: Message):
            print(f"Received message: {message.get_data_as_string()}")
        
        # Initialize and connect
        transport = SyncNats(servers=["nats://localhost:4222"])
        transport.connect()
        
        # Subscribe to a topic
        transport.subscribe("example.topic", message_handler)
        
        # Publish a message
        transport.publish("example.topic", "Hello, world!")
        
        # Clean up
        transport.close()
        ```
        
        ### Custom Transport Implementation
        
        You can implement your own transport by extending the `Transport` interface:
        
        ```python
        from fluxmq.transport import Transport
        from fluxmq.message import Message
        from typing import Callable, Awaitable, Any, Union
        
        class CustomTransport(Transport):
            async def connect(self) -> None:
                # Implementation...
                
            async def close(self) -> None:
                # Implementation...
                
            async def publish(self, topic: str, payload: Union[bytes, str]) -> None:
                # Implementation...
                
            async def subscribe(self, topic: str, handler: Callable[[Message], Awaitable[None]]) -> Any:
                # Implementation...
                
            async def unsubscribe(self, topic: str) -> None:
                # Implementation...
                
            async def request(self, topic: str, payload: Union[bytes, str]) -> Message:
                # Implementation...
                
            async def respond(self, message: Message, response: Union[bytes, str]) -> None:
                # Implementation...
        ```
        
        ## Testing
