Add Varbase Patches to the composer requirements and a Drupal CMS wiring script

Problem/Motivation

The recipe depends on patched contrib (notably drupal/canvas) but does not require the package that carries those patches, so it relies on whatever project template happens to be underneath.

There is also no way to prepare a plain drupal/cms codebase for it. composer require fails before the recipe is even downloaded, because every drupal/varbase_*_base it requires is 1.0.x-dev:

Could not find a version of package drupal/educare matching your minimum-stability

Steps to reproduce

1. composer create-project drupal/cms
2. composer require drupal/educare:1.0.x-dev
3. It fails on minimum-stability. Setting that alone then fails on a blocked composer plugin, and web/libraries/ stays empty.

Proposed resolution

Require vardot/varbase-patches in composer.json, above the Varbase base recipes.

Add scripts/drupal-cms-wiring.js (Node, no dependencies, idempotent, supports --dry-run), which sets what a stock drupal/cms lacks: dev stability, the allow-plugins and patches allowlist varbase-patches needs to run, the drupal-libraries sync into web/libraries/, and nodeLinker: node-modules for Yarn 4. Its values live in scripts/assets/drupal-cms.composer.json and scripts/assets/drupal-libraries.package.json, so the wiring can change without editing the script.

cd PROJECT_DIR_NAME/recipes/educare/scripts
node drupal-cms-wiring.js

composer require drupal/educare:1.0.x-dev -W
corepack enable && corepack yarn install

-W is needed because a partial update keeps the locked symfony/css-selector, which drupal/storybook conflicts with.

Verified on a stock Drupal CMS build: drupal/canvas resolves to 1.9.0 with its patches, all six libraries land in web/libraries/, and the recipe is in place. Nothing changes on a Varbase base.
