feat: add macOS support to installer and docs

- install.sh: detect Darwin, use Homebrew for packages/Node, Docker Desktop hint
- install.sh: portable realpath and bash 3-compatible confirm() for macOS
- docs/installer-support.md: add macOS (Darwin) / Homebrew to support matrix
- README.md: document supported platforms (Linux and macOS), Docker Desktop/Homebrew
- ci.yml: add installer-macos job (macos-latest, bash -n install.sh)
