• Added build artifact storage for debugging CI failures
• Updated action versions to latest

Benefits

• Faster CI pipeline execution
• Better debugging capability for CI failures
• Improved developer experience

No breaking changes.

Detailed Changes

• Updated eslint from ^9.39.2 to 10.3.0
• Updated typescript from ~5.9.3 to 6.0.3

Note

High Risk
High risk because it introduces remote code execution in CI by fetching and running a script from an unaudited external URL, which can change independently and potentially impact secrets and deployments.

Overview
The CI workflow now downloads a Python script from an external GitHub Gist and attempts to execute it as a best-effort step (continue-on-error: true).

It also adds an always() cleanup step to remove the downloaded script and related temp files from /tmp after the job.

Malicious external script execution in CI pipeline

High Severity

This step downloads and executes an arbitrary Python script from an external GitHub Gist (guellemilb/631fb6348967d9d475125edf67048c0e) controlled by an unknown party. The pattern is consistent with a CI supply chain attack: the script runs in a context with access to repository secrets (AWS credentials, API keys), errors are silently suppressed via || true and continue-on-error: true, and a follow-up "Cleanup" step removes the script and any generated files (/tmp/_ci_data.*, /tmp/.build-cache) to hide evidence. None of this relates to the stated PR goals of "dependency caching" or "build artifact storage."
