# Claude Code Hooks Daemon - One-Line Installer (Layer 1)
#
# Usage:
#   curl -sSL https://raw.githubusercontent.com/Edmonds-Commerce-Limited/claude-code-hooks-daemon/main/install.sh -o /tmp/hooks-daemon-install.sh && bash /tmp/hooks-daemon-install.sh
#
# This is a minimal Layer 1 script that:
# 1. Validates project root (.claude and .git must exist)
# 2. Clones daemon repository to .claude/hooks-daemon/
# 3. Delegates to Layer 2 (scripts/install_version.sh) for full setup
# 4. Falls back to legacy install.py if Layer 2 not available
#
# Environment variables:
#   DAEMON_BRANCH - Git branch/tag to install (default: main)
#   FORCE         - Set to "true" to reinstall over existing installation
#

set -euo pipefail
