Potential fix for code scanning alert no. 40: Workflow does not contain permissions

[Dargon789]

Potential fix for https://github.com/Dargon789/sequence.js/security/code-scanning/40

The fix is to explicitly define a minimal permissions block so that the GITHUB_TOKEN granted to this workflow is restricted to read‑only repository contents, which suffices for actions/checkout and typical dependency installation/build/test steps. The cleanest way is to add a single root‑level permissions: block that will apply to all jobs, rather than repeating it for each job.

Concretely, in .github/workflows/tests.yml, add:

name: tests
permissions:
  contents: read

directly under the existing name: tests line (line 3). This will limit all jobs (install, build, tests, and any uncommented future jobs) to read‑only access to repository contents unless they define their own permissions: block. No imports, methods, or further definitions are needed since this is purely a workflow configuration change and does not alter any job steps or functionality.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.

Reviewer's Guide

This PR updates the GitHub Actions tests workflow to explicitly configure minimal, read-only repository permissions for the workflow’s GITHUB_TOKEN, addressing a code scanning security alert.

File-Level Changes

Change	Details	Files
Constrain the tests GitHub Actions workflow token to minimal, read-only permissions at the workflow level.	Add a root-level permissions block directly under the workflow name Grant only contents: read access to the workflow’s GITHUB_TOKEN so all jobs inherit read-only repository access Rely on job-level overrides if any job later needs broader permissions	.github/workflows/tests.yml
