This PR introduces a comprehensive migration to the new uniform schema semantics (v0.2.42) and includes several infrastructure enhancements for better Docker and web server capabilities.

�� Schema Migration (Breaking Changes)

• Migrated to uniform schema v0.2.42 - Updated all PKL templates to use new schema format
• Template Updates: All resource templates (workflow.pkl, llm.pkl, python.pkl, exec.pkl, response.pkl, client.pkl) updated to use new schema semantics
• Field Naming: Changed from camelCase to PascalCase (e.g., name → Name, targetActionID → TargetActionID)
• Documentation: Updated all documentation files to reflect new schema format

🐳 Docker & Infrastructure Improvements

• WebSocket Support: Added proper WebSocket upgrade handling for proxy web applications
• Docker Build Enhancement: Implemented system-wide pip installation for better Python package management
• Dependency Updates: Updated key dependencies including Docker client, SQLite, and various Go packages

📚 Documentation & Testing

• Comprehensive Documentation: Updated all getting-started guides and resource documentation
• Test Coverage: Enhanced test coverage across multiple packages
• Examples: Updated tutorials and examples to use new schema format

🔧 Technical Details

• Files Changed: 97 files with 2,730 additions and 1,970 deletions
• Key Dependencies Updated:
  • github.com/kdeps/schema: v0.2.40 → v0.2.42

  • Added github.com/gorilla/websocket for WebSocket support

⚠️ Breaking Changes

This is a breaking change that requires users to update their existing PKL configurations to use the new uniform schema format. The migration involves:

• Converting field names from camelCase to PascalCase
• Updating template structures to match new schema requirements
• Reviewing and updating custom resource definitions
• Use 'kdeps upgrade' to upgrade to latest schema version and semantics as feasible.

🧪 Testing

• All existing tests updated and passing
• New tests added for WebSocket functionality
• Enhanced test coverage for schema migration components

📋 Migration Guide

Users should refer to the updated documentation for migration instructions from the old schema format to the new uniform schema format.
