v1.4.0 — per-environment defaults + ansi=off

New

• Per-environment defaults — the installer (and reset / first run) now seed the cheat sheet that matches your OS: Windows Terminal keys on Windows, terminal + readline + tmux on Linux, macOS Terminal / iTerm2 on macOS. Assets: windows.txt, linux.txt, macos.txt. shortcuts.txt stays as a generic fallback.
• // ansi = off — a data-file directive that disables all color and styling (bold/italic included). Use it when raw escape codes leak through, e.g. some SSH or WSL sessions. Like NO_COLOR, but it lives in the file.

Changed

• Trimmed the data-file header comment to 4 lines.
• Shorter shortcuts help output.

Upgrade with shortcuts update (never touches your edited shortcuts), or re-run the installer.
