Code Review
This pull request adds a new test suite in tests/test_io.py to verify the behavior of the get_category_color function across various categories. The reviewer identified a potential issue where tests could produce false positives in non-TTY or CI/CD environments because color constants might default to empty strings. To resolve this, the reviewer suggested mocking the color constants with distinct values during test execution to ensure robust and reliable assertions.

In non-TTY environments (such as CI/CD pipelines like GitHub Actions) or when NO_COLOR is set, the color constants in commando/utils/io.py are initialized to empty strings ("").
Because of this, importing and asserting against these constants directly in tests can lead to false positives (false greens). For example, if get_category_color has a bug and returns RED instead of CYAN, the assertion self.assertEqual(get_category_color("File Management"), CYAN) will compare "" with "" and pass successfully, masking the bug.
To make the tests robust and reliable in all environments, we should override these color constants with distinct mock values during the test execution.

🎯 What: Added unit tests for the previously untested get_category_color UI helper function in commando/utils/io.py.
📊 Coverage: The tests cover all conditional branches mapped to specific colors: CYAN (file/disk), MAGENTA (network/web), RED (process/system), GREEN (navigation/search), YELLOW (text/edit), and the fallback return BOLD. The tests also cover mixed-case string matches to ensure correct logic execution.
✨ Result: Test coverage for commando/utils/io.py is improved, providing reliable testing logic that safeguards against regressions when categorizing tags.
