Terminal metadata: Exposition

[CanadaHonk]

• Should we have a parent object (eg CLI.terminal.noColor) or bare in the namespace (eg CLI.noColor)?
• Functions (eg CLI.terminal.noColor()) or getters (eg CLI.terminal.noColor)?
• Interactivity:
  • Potential names: interactive, isInteractive, interactivity, nonInteractive, notInteractive, tty, isTty, isTTY, terminal, isTerminal, inTerminal
  • Deno used to have a isatty() function, but now is moving to isTerminal.
• No color:
  • Potential names: noColor, color, colorful, hasColor, shouldColor
  • We should probably just use noColor as it is essentially an opt-out preference; color could imply the user wants color which could not be true (rather than NO_COLOR stating the user explicitly does not want color). Also, this would then share the name of the environment variable "standard".
