Restrict the job token to read-only access.

This job inherits token permissions instead of declaring its required access. If repository defaults permit writes, the build receives unnecessary write permissions. Add permissions: { contents: read } to this job. GitHub recommends explicitly granting only the required permissions. (docs.github.com)

Based on learnings, restrict permissions for jobs that execute third-party build code.

Review comment at @.github/workflows/ci.yml at line 14:
Update the rust job to declare only the required GitHub token permission: read access to repository contents. Keep the permission scoped to this job rather than changing workflow-wide permissions.

Disable checkout credential persistence.

The pinned checkout action defaults persist-credentials to true. It leaves the token in local Git configuration until post-job cleanup. Set persist-credentials: false so subsequent Cargo build scripts cannot read that credential from Git configuration. These checks do not need authenticated Git writes. (raw.githubusercontent.com)

Based on learnings, disable credential persistence before executing third-party build code.

Review comment at @.github/workflows/ci.yml at line 28:
Set the checkout step’s persist-credentials option to false so the GitHub token is not retained in local Git configuration when subsequent build scripts run.

Pin rust-cache to the release commit, not the annotated tag object.

2201cc58… is the annotated tag object for v2.9.3. The commit that the tag points to is d1527c8f…. Pin the action to that commit. A tag object SHA can fail to resolve as an action ref, which can block the matrix jobs.

Review comment at @.github/workflows/ci.yml at line 36:
Update the `Swatinem/rust-cache` reference in the workflow to use the release commit `d1527c8f67ef9af357290475d4af4b0fab8f12e0` instead of the annotated tag object, preserving the `v2.9.3` version comment.
