v1.1.2

• Off a Mac, all three hooks now exit before doing anything. The PATH hook already said nothing there, but it still wrote a PATH line to CLAUDE_ENV_FILE when it found Linuxbrew gnubin directories, putting one GNU build ahead of another. warn-old-bash.sh had no platform check, so a distribution's bash 4.4 or an older Git for Windows got "Fix: brew install bash".
• The README has a new "Off a Mac" section. The copy-in route now says what the env block does elsewhere: harmless on Linux, but on Windows a bare CLAUDE_CODE_SHELL=bash may resolve to the WSL launcher (read from the 2.1.296 binary, not tested on Windows). A team on mixed OSes should commit only the hooks block.
