feat: Deploy released Editor versions to GitHub Pages

[fantonangeli]

Description

Deploy released Editor versions to GitHub Pages.

Motivation

The Editor is currently deployed to Netlify from main.

This is useful for development and pull request previews, but the Open Workflow Specification website should link to a deployed released version of the Editor instead of showing unreleased changes from main.

Proposed Implementation

Deploy the Editor to GitHub Pages as part of the release process.

The deployment should:

• Build the Editor from the exact Git tag associated with the release, not from main.
• Be triggered as part of the release or publish workflow.
• Keep the deployments permanently available.

Definition of Done

• Implementation: Fully implemented according to the Open Workflow spec.
• Unit Tests: Comprehensive unit tests are included and passing.
• Integration Tests: Verified within the monorepo and target environments (Web/VS Code).
• Documentation: Updated README.md, ADRs, or official docs.
• Performance: No significant regression in editor responsiveness.
• Accessibility: UI changes comply with accessibility standards.
