# Setup Go workspace for LiveTemplate local development
#
# This creates a go.work file that automatically uses local versions
# of all LiveTemplate repositories without modifying go.mod files.
#
# Usage:
#   ./setup-workspace.sh          # Create workspace
#   ./setup-workspace.sh --clean  # Remove workspace
#
# Requirements:
#   - Go 1.18+ (for workspace support)
#   - All repos cloned as siblings in this directory
