Initialize Varbase Performance Base recipe

Problem/Motivation

This recipe manages default performance optimization modules, caching configurations, and speed enhancements for Varbase. It includes page caching, asset aggregation, image optimization via ImageMagick, and WebP conversion support.

Proposed resolution

Initialize the varbase_performance_base recipe with the following:

• recipe.yml Installs page_cache, dynamic_page_cache, imagemagick, imageapi_optimize, and imageapi_optimize_webp. Applies default simpleConfigUpdate actions for system.performance, system.image, and imagemagick.settings.
• composer.json Declares contrib dependencies with versions aligned to the Varbase 11.x ecosystem.
• README.md Documents installation and performance features.
• .gitlab/ Issue and merge request templates following the standard Varbase recipe structure.
• logo.png Standard Varbase product logo.
