Potential fix for code scanning alert no. 9: Workflow does not contain permissions

[gerlero]

Potential fix for https://github.com/gerlero/fronts/security/code-scanning/9

To resolve this issue, an explicit top-level permissions block should be added to the workflow. This restricts the default permissions of the GITHUB_TOKEN to the least privilege that covers the needs of the workflow. Here, none of the jobs appear to need write access: actions like checkout, Ruff linting/formatting, mypy, pytest, and uv build do not require write permission to repository contents. The only exception may be the use of codecov/codecov-action, but uploading coverage just requires reading from the repository and using the secret; it does not adjust the repo state.

Therefore, the best fix is to add at the root - directly after the name: CI line (before on:) - the line:

permissions:
  contents: read

This will apply to all jobs unless overridden and follows GitHub's recommendation for the minimum baseline. If any job later requires greater permissions, a more specific permissions block can be applied on that job only.

Files/Regions to change:

• .github/workflows/ci.yml, after the name: CI line (line 1), insert the permissions block.

What is needed:

• No imports/method definitions/variable definitions required; only YAML key insertion.
