[BUG] Parallel GH actions are suggested but the example shows the opposite

[staticf0x]

Bug Description

There is:

No parallelization detected
Enable parallel job execution

but then the example section shows this:

- name: Run linters
        run: |
          black --check .
          isort --check .
          ruff check .

If parallel processing is suggested, then the example section should reflect that - all these linters can be run in parallel.

The example actually does demonstrate parallel execution. lint and test are separate jobs that run in parallel by default in GitHub Actions. Only build waits for both via needs: [lint, test].

The issue raised is about the three linters (black, isort, ruff) running sequentially within the lint job's single run: block. Running fast linters sequentially in one step is standard practice, splitting them into separate parallel jobs would add 3x checkout + setup overhead for negligible gain.

That said, the parallelization could be made more explicit with a comment in the example. Something like:

 jobs:
-  lint:
+  lint:  # lint and test jobs run in parallel
     name: Lint Code
     runs-on: ubuntu-latest

Suggesting a PR with this fix if it sounds reasonable.
