v1.0.0

Initial release.

• settings.json env block that switches Claude Code's Bash tool from zsh to bash 5.
• SessionStart hook that puts Homebrew's gnubin directories first on the Bash tool's PATH, so sed, date, stat, awk, tar, which and xargs resolve to the GNU builds.
• Installable as a plugin via /plugin marketplace add Baune8D/claude-code-macos, or by copying the files into a repository.
• Warns once at session start when the Bash tool is not running bash, or when the bash that won is still Apple's 3.2.
• MIT license.
