Save workflow logs from recent commits for SWE Agent access

[Copilot]

Enables GitHub Copilot coding agent to access workflow logs from the two most recent commits in a PR for debugging failed builds and tests.

Changes

• .github/scripts/download-workflow-logs.sh: Shell script queries GitHub Actions API via gh CLI to download workflow run logs from the two most recent commits, saving them to workflow-logs/ with naming pattern {commit-hash}_{run-id}_{workflow-name}.log

• .github/workflows/copilot-setup-steps.yml:

  • Added actions: read permission for workflow API access
  • Added log download step at workflow end with continue-on-error: true
  • Passes GH_TOKEN for authentication

• .gitignore: Excludes workflow-logs/ from version control

Mechanism

When running in a PR context:

1. git log -n 2 retrieves latest two commit hashes
2. gh run list --commit <hash> finds all workflow runs per commit
3. gh run view <run-id> --log downloads each workflow's complete log
4. Logs saved to $GITHUB_WORKSPACE/workflow-logs/ for SWE Agent access

Script gracefully handles missing runs, incomplete logs, and non-PR contexts.
