/**
 * CLI context module - consolidated global state for CLI operations.
 *
 * Creates a CliContext object from argv and environment, providing:
 * - Output configuration (format, color, verbosity)
 * - TTY detection
 * - Color functions that respect color settings
 * - Prefixes for different message types
 *
 * @example
 * ```ts
 * import { createContext } from './cli/context.js';
 *
 * const ctx = createContext(process.argv.slice(2), process.env);
 * console.log(ctx.colors.green('Success!'));
 * ```
