feat(blockly): Phase A foundation - Blockly setup, custom blocks, and generators

- Install blockly package (~500KB)
- Create BlocklyWorkspace React component with serialization
- Define custom Noodl blocks (Input/Output, Variables, Objects, Arrays)
- Implement JavaScript code generators for all custom blocks
- Add theme-aware styling for Blockly workspace
- Export initialization functions for easy integration
