All EAS builds fail at "Prepare project" — tar extraction error (exit code 2) since 22/03/2026 — no code changes

### Summary

Since approximately 22/03/2026 at 10 PM (UTC+1), every EAS build fails at the "Prepare project" phase with:

tar -C /home/expo/workingdir/build --strip-components 1 -zxf /home/expo/workingdir/project.tar.gz exited with non-zero code: 2

15+ consecutive builds have failed. The last successful build ran on 22/03/2026 at 10:23 AM using the exact same codebase, .easignore, and eas.json. No
code changes were made between the last successful build and the first failure.

Steps to reproduce

1. Run eas build --platform android --profile preview on Windows 11 with EAS_NO_VCS=1
2. Archive uploads successfully (~839 KB)
3. Build fails immediately at "Prepare project" with tar exit code 2

What I have tried

- Switching build images: latest, default, sdk-54
- Running with --clear-cache
- Excluding additional directories via .easignore
- Fresh npm install
- Local tar creation and extraction — works fine

- Latest failure: https://expo.dev/accounts/antoinevdsw/projects/happy7-stars/builds/bff2a33f-b8c5-4b1a-a75d-cf720f56379a

The failure appears to be server-side: nothing changed between builds, local tar works, and archive size is consistent.
