chore(cmd): refactored main program

[fredbi]

Another baby step forward:

• refactored error and flags handling in main program
• this improves testability, so we add a unit test for main

There is still some room for improvement (coverage, I/O injection for better control in a test environment). Essential options in main are covered by tests.

Pull request overview

This PR refactors the main program to improve testability by extracting error handling and flag management into testable functions. The changes introduce a commandContext struct to hold CLI flags and I/O streams, an execute() function that can be independently tested, and comprehensive unit tests covering the main execution paths.

Key changes:

• Extracted main logic into testable execute() function with dependency injection for I/O
• Introduced commandContext and commandFlags structs for better organization
• Added comprehensive unit tests for main program execution paths
