feat(blockly): Phase C Step 7 COMPLETE - Code generation & port detection

Wired up complete code generation and I/O detection pipeline:
- Created BlocklyEditorGlobals to expose detectIO and generateCode
- Runtime node accesses detectIO via window.NoodlEditor
- Dynamic port updates based on workspace changes
- Full integration between editor and runtime
- Auto-initialization via side-effect import

Complete flow now works:
1. User edits blocks in BlocklyWorkspace
2. Workspace JSON saved to node parameter
3. IODetector scans workspace for inputs/outputs/signals
4. Dynamic ports created automatically
5. Code generated for runtime execution

Next: Testing and verification
