Pins the default GITHUB_TOKEN to contents: read on 5 workflows in .github/workflows/ that don't call a GitHub API beyond the initial checkout.

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 the workflows in
.github/workflows/ that don't call a GitHub API beyond the initial
checkout. The other workflows in this directory are left implicit
because they need write scopes that a maintainer is better placed
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 if the default ever widens, and are credited
per-file by the OpenSSF Scorecard Token-Permissions check.

YAML validated locally with yaml.safe_load.
