fix: default to 'average' variation when navigating to package managers

[vltbaudbot]

Problem

When navigating away from the package managers view (e.g., to task runners or registries) and then clicking back, the page defaults to the "clean" variation instead of "average".

This is inconsistent with the initial page load, which uses sortVariations() to pick the first variation — which is "average".

Root Cause

In routes.tsx, the package-managers index route was hardcoded to redirect to clean:

{ index: true, element: <Navigate to="clean" replace={true} /> }

Meanwhile, the App.tsx useEffect that handles the initial / → /package-managers/{variation} redirect correctly uses sortVariations(), which puts "average" first.

When the user navigates away and clicks back, the NavLink goes to /package-managers (no variation), hitting the index route redirect — which was going to clean instead of average.

Fix

Changed the package-managers index route default from clean to average to match the intended behavior.

Changes

• app/src/routes.tsx: Changed Navigate to="clean" → Navigate to="average"
