Elevated contents: write on pull_request_target workflow

Medium Severity

Adding contents: write to a pull_request_target-triggered workflow grants the GITHUB_TOKEN write access to repository contents for PRs originating from forks. This is a well-documented attack vector — recent incidents (Trivy breach, hackerbot-claw campaign, March 2026) exploited exactly this pattern to push malicious code and exfiltrate secrets. A PR validation workflow typically only needs to read content and comment on PRs, making contents: write broader than expected. Flagged per the review rules' security vulnerability guidelines.
