Module error 

Unified error types for nros

This module provides comprehensive error types that align with rclrs patterns while maintaining no_std compatibility for embedded systems.

Error Types

• NanoRosError - Main unified error type
• RclReturnCode - RCL-compatible error codes
• ErrorContext - Context information (topic, service, node names)
• NanoRosErrorFilter - Trait for filtering expected errors
• TakeFailedAsNone - Trait for converting take failures to Option

Example

use nros_core::{NanoRosError, RclReturnCode};

fn publish_message() -> Result<(), NanoRosError> {
    Err(NanoRosError::timeout())
}

let result = publish_message();
assert!(result.unwrap_err().is_timeout());
