Fixes #4

Summary

  • Implement multi-stage Node.js build to reduce footprint from 265MB to 140MB
  • Add comprehensive cache cleanup including 1.4GB Playwright cache removal
  • Optimize layer structure with combined installations and in-layer cleanup
  • Maintain readable separation between Chrome and Playwright installations

Performance Improvements

  • Total size reduction: 1.67GB (44.3% smaller: 3.77GB → 2.10GB)
  • Layer optimizations: Reduced from multiple large layers to efficient consolidated layers
  • Cache cleanup breakthrough: Eliminated 1.4GB of unnecessary Playwright cached data
  • Multi-stage build: Node.js installation optimized by 47% (265MB → 140MB)

Test plan

  • Build new Docker image successfully
  • Verify all browsers work: Chrome, Firefox, WebKit, Chromium
  • Confirm PHPUnit functional tests still pass
  • Test Playwright functionality across all browsers
  • Validate CI/CD pipeline performance improvements

@justafish I can't remember how to check out a PR merge commit locally (c57cb92e27f13e0fa779cbc96d544ff57d1d7632 -> pull/5/merge), but you could check it out and tag it as something experimental to publish... although I just realized the tags require v.... So maybe v1.1.0-beta1 or something
