Potential fix for code scanning alert no. 1: Workflow does not contain permissions

[movsal08]

Potential fix for https://github.com/movsal08/IdempotencyKey/security/code-scanning/1

In general, the fix is to explicitly declare a permissions block for the workflow or the specific job, granting only the minimal scopes required. For a simple CI workflow that only checks out code and runs build/tests, read-only access to repository contents is sufficient.

The best targeted fix here is to add a permissions block at the workflow root (top level, alongside name and on) specifying contents: read. This applies to all jobs that don’t override permissions and matches CodeQL’s suggested minimal starting point. No other functionality changes are required, and no additional steps in the shown snippet require write access.

Concretely, in .github/workflows/ci.yml, insert:

permissions:
  contents: read

between the name: CI line and the on: block (i.e., after line 1 and before line 3). No imports or other definitions are needed because this is pure workflow configuration.
