Add test coverage for context propagation in main package

[coderabbitai]

Background

During the review of PR #15 (#15), it was identified that there are no tests for the main package, particularly for validating context propagation.

Issue Description

The current implementation in main.go correctly instantiates a background context and passes it to cmd.Execute, which aligns with best practices. However, there are no tests for the main package or tests specifically validating context propagation.

Tasks

• Add tests for the main package
• Verify that context is properly propagated to cmd.Execute
• Include tests for context cancellation or timeout scenarios if applicable

Example starter snippet for a test could be:

func TestMainContextPropagation(t *testing.T) {
    ctx, cancel := context.WithCancel(context.Background())
    defer cancel()

    // Potentially simulate a scenario or capture behavior from cmd.Execute that confirms
    // context propagation. This is a placeholder for the actual test logic.
    cmdOutput := captureCmdExecute(ctx) 
    if !validateOutput(cmdOutput) {
        t.Error("failed to verify proper context propagation in cmd.Execute")
    }
}

Additional Notes

This improvement was deferred from PR #15 to keep the PR size manageable.
