test: add unit tests for pkg/version package

[mason5052]

Description of Change

Problem: The pkg/version package has no unit test coverage. The package provides binary version, name, and development mode detection used throughout the application.

Solution: Add comprehensive unit tests for all three exported functions (GetBinaryVersion, IsDevelopMode, GetBinaryName) covering all code paths including default values, custom values, and combined version-revision formatting.

Hi, just a friendly ping -- this is a small test-only PR (8 tests for pkg/version) with no production code changes. Happy to adjust anything if needed. Thanks for your time!

hey @mason5052

thanks for the PR, requests are accepted with a slight delay due to the use of sprints in product development, these are not always urgent changes, I hope for your understanding
