AI Coding Instructions

• Keep useColor exported so tests can access the same color behavior as lib/command.js.
• Test color-related behavior through useColor rather than duplicating its decision logic in test files.
• Avoid adding production call sites outside lib/command.js unless the module boundary is intentionally changed.
• Account for runtime environment settings that may affect whether color output is enabled.
