Faster builds with layer caching

Builds now reuse dependency layers when your lockfile has not changed. Most projects see repeat builds finish two to three times faster.

Details

• Works with package-lock.json, pnpm-lock.yaml, yarn.lock, poetry.lock, and requirements.txt
• The cache is kept per branch, so preview builds do not evict production layers
• Clear it from Settings → Build or with cloud build --no-cache

No configuration is needed. Caching is on for every project.
