Long dependency installation steps run before quick lint/type-check steps. Reordering to fail fast reduces wasted compute.

Detection
---------

``heuristic`` — Structural comparison across multiple jobs or steps.

Examples
--------

**Non-compliant:**

.. code-block:: yaml

   jobs:
     ci:
       steps:
         - uses: actions/setup-node@v4
         - run: npm install
         - run: npm run lint

**Compliant:**

.. code-block:: yaml

   jobs:
     ci:
       steps:
         - uses: actions/setup-node@v4
         - run: npm run lint
         - run: npm install
         - run: npm test

**Fix**: Move fast-fail steps (lint, type-check) before slow install steps so broken code is rejected before wasting time on dependency installation.
