/// Main error type for all RocketMQ operations
///
/// This enum provides a unified error system across all RocketMQ crates.
/// Each variant represents a logical category of errors with rich context information.
///
/// # Design Principles
/// - **Semantic**: Each error clearly expresses what went wrong
/// - **Performance**: Minimal heap allocations, use of &'static str where possible
/// - **Debuggability**: Rich context for production debugging
/// - **Ergonomics**: Automatic conversions via From trait
///
/// # Examples
///
/// ```rust
/// use rocketmq_error::RocketMQError;
/// use rocketmq_error::RocketMQResult;
///
/// fn send_message(addr: &str) -> RocketMQResult<()> {
///     // Create a network error
///     if addr.is_empty() {
///         return Err(RocketMQError::network_connection_failed(
///             "localhost:9876",
///             "empty address",
///         ));
///     }
///     Ok(())
/// }
///
/// fn authenticate_user(username: &str) -> RocketMQResult<()> {
///     // Create an authentication error
///     if username.is_empty() {
///         return Err(RocketMQError::user_not_found(""));
