Fix flaky e2e tests: github-models-integration and docker-utils

[Copilot]

Two e2e tests were intermittently failing in CI due to timing and tar archive issues.

github-models-integration.test.ts

The "should show helpful error when GITHUB_TOKEN is missing" test timed out at 10s before the command could complete plugin loading and file scanning. The error message also appears in both stdout and stderr depending on output buffering.

• Increased timeout to 60s
• Check combined stdout + stderr for error message

docker-utils.ts

The addDirectoryToPack function created a root directory entry with name '/' when relativeTo was empty, which could cause extraction issues:

// Before: creates entry with name '/'
pack.entry({ name: relativeTo + '/', type: 'directory', ... });

// After: skip root directory entry
if (relativeTo !== '') {
  pack.entry({ name: relativeTo + '/', type: 'directory', ... });
}

docker-utils.test.ts

• Added .filter((f) => f.length > 0) to handle empty strings in file list parsing

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

work on deflaking e2e tests, a few of them are flaky, and your task is to detect a flaky test, and then fix it
