Implement the NO_COLOR standard (https://no-color.org/) for CLI output.
When NO_COLOR is set (to any value), ANSI color codes are disabled.
Changes:
- Add init() to check NO_COLOR and TERM=dumb environment variables
- Add ColorEnabled() to query current color state
- Add SetColorEnabled() to programmatically enable/disable colors
- Modify AnsiStyle.Render() to return plain text when colors disabled
- Update UseASCII() to also disable colors (consistent with ASCII mode)
- Add comprehensive tests for color enable/disable functionality
Usage:
NO_COLOR=1 core dev status # Runs without color output
TERM=dumb core dev status # Also disables colors
