Start a 4.0.x branch for Varbase Components to support Drupal Canvas and Varbase 11.0.x

Problem/Motivation

With the adoption of Drupal Canvas and the release of Varbase 11.0.x, the Varbase Components module needs to align with a fully component-driven rendering architecture.

Drupal Canvas introduces:

• Component tree rendering
• Canvas content templates
• Slot-based layouts
• View mode–driven rendering logic

To properly support this architecture, Varbase Component must evolve to ensure compatibility with:

• Canvas-based page and content templates
• Single Directory Components (SDC)
• Modern Twig structure and component metadata
• Varbase Starter and Varbase 11.3 requirements

Developing these updates within the current branch would constrain architectural improvements and complicate version alignment.

Proposed resolution

• Create a new 4.0.x branch for Varbase Components.
• Align the module with Drupal Canvas rendering architecture.
• Ensure compatibility with Varbase 11.0.x.
• Refactor component integration where necessary to support Canvas content templates and slot-based rendering.
• Maintain previous branches for stability in non-Canvas implementations.

This will establish a clean, forward-looking services for component-driven development in the Varbase 11 ecosystem.
