# Docker E2E Tests
#
# This workflow runs e2e tests against the Docker container.
# It is triggered by:
# - push: On push to main branch
# - pull_request: On all pull requests
# - workflow_dispatch: Manual trigger for testing
#
# The workflow builds the Docker image locally using GitHub Actions cache (type=gha)
# which is automatically shared with the "Docker Image Build and Publish" workflow.
# This allows both workflows to run in parallel while still benefiting from
# shared cache, making the second build very fast on cache hits.
