[0.3.0]

Enhanced Extep struct with tasks field to track pending async operations
Updated run/2 and run/3 to automatically await pending tasks before execution
Updated return/2 and return/3 to handle pending tasks before returning results
Enhanced error handling to properly shut down tasks when pipeline is interrupted
Improved function guards and type specifications for better pattern matching

The async/2 function runs checker functions asynchronously without modifying context
The async/3 function runs mutator functions asynchronously and stores results under given keys
All async tasks are executed in parallel and results are merged in order when await/1 is called
Pipeline stops at first async task failure, with proper task cleanup
Backward compatibility maintained - existing synchronous pipelines work unchanged

Added label_error option to return/3 for better error debugging and identification
Added extensive test coverage for label_error functionality

Improved run/2 documentation with clearer explanations of:
- Function return values and their effects
- Error message labeling for named vs anonymous functions
- Pipeline behavior and when functions execute
Improved run/3 documentation with detailed explanations of:
- Parameter requirements and usage
- Context mutation behavior
- Error scenarios with step-by-step breakdowns
- Halt scenarios and pipeline flow control
Enhanced return/3 documentation with comprehensive examples covering:
- Successful pipeline scenarios
- Error handling with and without labels
- Halt message handling
- Different error labeling behaviors
Improved README.md API documentation with label_error usage examples
