Fixes disk space exhaustion during Docker builds in GitHub Actions CI by using BuildKit cache mounts for the yarn cache directory.

Changes

  • Modified Dockerfile to use --mount=type=cache for yarn cache
  • Yarn cache is now excluded from Docker image layers
  • Cache persists between builds on the same runner

Benefits

  • Fixes "no space left on device" errors in CI
  • Reduces final image size (yarn cache not included)
  • Maintains or improves build performance (persistent cache)

Ticket: VL-3537

fix: use cache mount for yarn to prevent disk space exhaustion
23f8855 
Excludes yarn cache from Docker image layers by using BuildKit cache mounts.
This prevents "no space left on device" errors during CI builds while
maintaining fast build times through persistent cache between runs.
