#!/bin/bash
# Wrapper script to push to development and automatically trigger GitLab pipeline

# Usage: ./push-dev.sh [options] [git push options]
# Examples:
#   ./push-dev.sh                    # Auto-detect if build is needed
#   ./push-dev.sh --skip-build       # Force deploy only (reuse existing images)
#   ./push-dev.sh --force-build      # Force full build even if not detected as necessary
#   ./push-dev.sh --skip-build -f    # Deploy only with force push

# Parse flags
