CodeAnt-AI Description

Use zstd compression for Docker image artifacts to speed up frontend CI

What Changed

• Saved the built frontend CI Docker image using zstd compression (.tar.zst) instead of gzip (.tar.gz)
• CI jobs now download the .tar.zst artifact and decompress it with zstd before loading the image, so all frontend test, lint, and build steps load the compressed image
• Artifact upload/download and image load commands reflect the new .tar.zst filename

Impact

✅ Shorter frontend CI image save/load time
✅ Faster frontend CI job startup
✅ Smaller artifact transfer time

Sequence Diagram

This PR changes the frontend CI image artifact format from gzip to zstd to speed up save and load steps. The build job now uploads a zstd-compressed Docker image, and each downstream frontend job downloads, decompresses, loads, and reuses it for checks.

1 minute faster and ~100MB lighter for the frontend-build process. Not bad, not bad
