fix: correct WebAssembly serialization format for members

**Motivations :**
- Fix WebAssembly serialization error: 'invalid type: sequence, expected a map'
- WebAssembly expects object/map format, not array format
- Ensure proper data structure for create_new_process function

**Modifications :**
- Reverted members conversion from array back to object format
- WebAssembly expects map/object structure, not array sequence
- Updated debug logging to show object keys and sample entries
- Maintained proper member data structure for WebAssembly compatibility
