#!/usr/bin/env bash
# install.sh — install webtest-orch into Claude Code skill dirs.
#
# Copies (or symlinks) this directory into ~/.claude/skills/webtest-orch/
# and verifies that required MCP servers are registered.
#
# Usage:
#   bash install.sh                  # copy
#   bash install.sh --symlink        # symlink (preferred during development)
#   bash install.sh --check-only     # verify state, change nothing
#
