Pins the default GITHUB_TOKEN to contents: read on 2 workflows in .github/workflows/ that don't call a GitHub API beyond the initial checkout.

Left implicit because they reference GITHUB_TOKEN / use a write-scope action / trigger on pull_request_target. Best declared by a maintainer: update-quick-start-module.yml.

Why

CVE-2025-30066 (March 2025 tj-actions/changed-files supply-chain compromise) exfiltrated GITHUB_TOKEN from workflow logs. Pinning per workflow caps runtime authority irrespective of the repo or org default, gives drift protection if the default ever widens, and is credited per-file by the OpenSSF Scorecard Token-Permissions check.

YAML validated locally with yaml.safe_load on each touched file.

Pins the default GITHUB_TOKEN to contents: read on workflows that don't
call a GitHub API beyond the initial checkout. Other workflows that need
write scopes are left implicit for a maintainer to declare.

Motivation: CVE-2025-30066 (March 2025 tj-actions/changed-files
compromise) exfiltrated GITHUB_TOKEN from workflow logs. Per-workflow
caps bound runtime authority irrespective of repo or org default,
give drift protection, and are credited per-file by the OpenSSF
Scorecard Token-Permissions check.
