# Script: fix-duplicate-triggers.sh
# Purpose: Remove duplicate triggers from table files
# Date: 2025-11-24
# Author: Architecture-Analyst
#
# This script comments out CREATE TRIGGER statements from
# table definition files, as they should only exist in
# separate trigger files (ddl/schemas/*/triggers/*.sql)
