Introduce ANSI color support for the hemlock interpreter and hemlockc compiler to provide a more polished and user-friendly terminal experience: - Create terminal.h with ANSI color macros and TTY detection - Add sexy ASCII art tree logo to REPL header - Colorize help text with section headers, options, and examples - Add colored error messages (red "error:" prefix) - Add progress indicators in compiler verbose mode ([1/5], [2/5], etc.) - Style file info output with highlighted values and formats - Color the REPL prompt (green ">>>") - Auto-detect color support (honors NO_COLOR, checks TERM and isatty)
