[WIP] Create Collaborative editing documentation

[Copilot]

Collaborative Editing Documentation Implementation Plan

Based on the issue requirements and existing repository patterns, I will create comprehensive documentation for the Collaborative editing feature using templates from .github/instructions/ and following the established patterns in the repository.

Current Analysis

• Explored repository structure and existing patterns
• Found existing references to collaborative editing in navigation (mkdocs.yml)
• Found existing permissions documentation (docs/permissions/collaboration_policies.md)
• Reviewed template files and documentation standards
• Identified PHP API references already exist in docs/api/php_api/php_api_reference/
• Installed Python dependencies for documentation building

Implementation Checklist

Core Feature Documentation

• Create main landing page: docs/content_management/collaborative_editing/collaborative_editing.md
• Create comprehensive feature guide: docs/content_management/collaborative_editing/collaborative_editing_guide.md
• Create installation guide: docs/content_management/collaborative_editing/install_collaborative_editing.md

API & Technical Documentation

• Create events reference: docs/api/event_reference/collaboration_events.md
• Create search criteria reference: docs/search/collaboration_search_reference/collaboration_criteria.md
• Create sort clauses reference: docs/search/collaboration_search_reference/collaboration_sort_clauses.md

Code Examples & Migration

• Create PHP code samples in code_samples/collaboration/src/
• Create data migration YAML examples in code_samples/data_migration/examples/collaboration/
• Ensure all code samples pass PHPStan analysis

System Integration Updates

• Update navigation in mkdocs.yml (already partially exists)
• Update main page LTS highlight in docs/index.md
• Update permissions documentation (already exists at docs/permissions/collaboration_policies.md)
• Cross-reference related features

Supporting Materials

• Create screenshots for feature documentation
• Update product guides page to include collaborative editing

The documentation will follow the established patterns from the Discounts feature and other existing features, ensuring consistency with the repository's standards and architecture.
