Module terminal 

Terminal mode detection for streaming output.

This module provides terminal capability detection to control whether ANSI escape sequences (cursor positioning, colors) should be emitted.

Terminal Modes

• Full: Full ANSI support including cursor positioning, colors
• Basic: Basic TTY with colors but no cursor positioning (e.g., TERM=dumb)
• None: Non-TTY output (pipes, redirects, CI environments)

Environment Variables

The detection respects standard environment variables:

• NO_COLOR=1: Disables all ANSI output
• TERM=dumb: Enables Basic mode (colors without cursor positioning)
• CLICOLOR=0: Disables colors on macOS
• CLICOLOR_FORCE=1: Forces colors even in non-TTY
