# =============================================================================
# RuvBot - Google Cloud Build CI/CD Pipeline
# =============================================================================
# Trigger: Push to main branch or tag
# Deploy to: Cloud Run (serverless)
#
# Cost optimization:
# - Uses e2-standard-2 machine for builds
# - Caches npm dependencies
# - Multi-stage Docker builds
# =============================================================================
