- Introduced `AddFunc` method to the `Job` struct for adding Go functions as job executions, allowing for dynamic execution of functions with specified arguments.
- Enhanced internal execution handling to register functions in a global registry, ensuring proper cleanup after execution.
- Implemented `ExecuteFunc` method in the `Goroutine` struct to handle the execution of registered functions, including error handling and context management.
- Added comprehensive unit tests for `AddFunc`, verifying function registration, execution, and memory cleanup post-execution.
- Updated related documentation to reflect the new functionality and usage patterns for adding and executing Go functions within the job system.
