#!/usr/bin/env bash
# install.sh — Install PHP rules to ~/.claude/rules/
#
# Usage:
#   ./install.sh           # Install common + php rules
#   ./install.sh --help    # Show usage
#
# Claude Code plugins distribute agents, skills, commands, and hooks
# automatically via /plugin install. However, rules must be installed
# manually. This script handles that.
